Video Transcript for Polar Hardware Enclosed Trailer Parts - Doors - PLR1902 Review

Today we're going to be taking a look at the ramp door hinge from Polar 00:00:05 hardware. This hinge is designed for ramps or heavy access doors on your trailers. It's made from a very strong and durable steel construction. It's going to have that plain or raw finish, which allows for easier welding for the installation. You'll notice that right here it does come with a grease fitting. That's going to allow for long life and smooth operation.

Once this is installed all you have to do is attach a grease gun to that, pump in some grease. That's going to lubricate the internal pin and it's just going to allow for really nice, smooth operation. Overall, it's going to increase the life of the hinge. A few measurements to go over with you real quick. The thickness of the plate right here is going to be 1/4-inch steel. Going this direction, that plate is going to measure 4-inches.

Going this direction, it's going to measure 2 1/4-inches. The length edge to edge, we're looking at a measurement of 8 1/4-inches. Then the ends are going to have a diameter of right around 1-inch. Really nice operation though. It's going to rotate all the way.

Very easy to do and again if that ever gets tight or whatever, hook up a grease gun, pump in the grease, it's going to lubricate the internal components. That's going to do it for today's look at the ramp door hinge from Polar hardware.

I have an older "Lark" trailer that had 3 hinges similar to these ramp door hinges I purchased from e-trailer. Two out of three had broken over the years. Lark was of no help when I contacted them. I went to several places that are known here in Orlando for trailer repair. They want a kings ransom to replace them. So, I located these hinges on e-trailer.com I ordered them and they were promptly delivered. Examined them closely and they are well made, and also have the grease nipple for keeping them lubricated. A local metal shop came and welded them on my trailer. These hinges are perfect. If you have a car-hauler or any trailer for that matter - you won't be disappointed in these hinges. No, I was not paid for this endorsement - and I did paid full price for the hinges. Good value for my money.



by:

My parts were promptly shipped, in good condition upon arrival. Perfect fit for my application, and have had no problems over the last year. Application was for a 2010 piece American car hauler rear door ramp hinges.



by:

I received my Ramp Door Hinge and it is heavy duty and was packaged with care. I even called customer service to check arrival time and the individual who helped me was very kind. First of all a person answered the phone, second she did not ask for an order number just my name and she was able to tell me exactly what was going on with my order and when it should arrive. My order arrived exactly when she told me. I am hoping to get it welded on today and if I am able I will try to return here and post pictures. Thank you guys.

After a year of use my rear ramp door hinge is still holding up as if it was just installed yesterday. There is no slack nor looseness what so ever. Its a great product, very durable in deed. Definitely made the right choice with that purchase. 100 still satisfied.



by:

The hinges were heavier than I expected. They were very easy to weld in and best. Of all, they have a grease fitting. I believe these will last the life of the trailer.

Great value on heavy duty hinges. I had a custom Bifold landscape ramp built. And used 8 of these hinges. Four at the body and four at the Bifold.

OK fine, you need another installed so you dont get locked in while inside FYI



by:

Ordered these to use on a landscaping trailer for a rear ramp gate that will hold at least 800 pounds got 3 of them to spread the weight out, seemed heavy duty and they are, these are big hinges in a good way. The zerk fitting is a great plus! makes it easier than fabricating your own hinges. The square plate makes it easy to align and gives you enough material to weld to.Price was goog shipping was fast, customer service is always excellent.

See what our Experts say about this Polar Hardware Trailer Door Hinges

  • Will Polar Hinge # PLR2216 Support a Ramp Door?
    The Square Corner Hinge with Reverse Bracket - Zinc Plated Steel - 16" # PLR2216 are not rated for a weight limit. For a ramp door, I recommend instead using the Ramp Door Hinge - Steel # PLR1902 which is a much thicker metal and a stronger pin. This is designed for that function and needs to be welded in place. The Square corner hinge although easier to install would risk hardware failing as they aren't designed to hold weight beyond the door itself.

  • Recommended Ramp Hinge to Support Weight of Ford 4000 Tractor
    I recommend looking at the Polar Ramp Door Hinge # PLR1902. This is a heavy duty steel hinge that features a plain finish for easier welding and also includes a grease fitting to allow for a longer life and smoother operation. This hinge does not have a specific weight rating, but 3 of the hinges on your ramp door will be more than enough to support the weight of your Ford 4000 Tractor. I have attached a short video demonstration on this product that you can also check out.

  • Is Hinge Pin of Polar Ramp Door Hinge # PLR1902 Removable?
    The Polar Ramp Door Hinge - Steel # PLR1902 is not removable as removing that pin would compromise the zerk grease fitting and seals related to it. I confirmed this with my tech contact at Polar.

  • Does the Polar Ramp Door Hinge # PLR1902 Have 2 Plates for Welding
    The Ramp Door Hinge # PLR1902 that you referenced does not come with 2 of the plates for welding. You will weld the plate to one surface and the outside ends of the pin to the other for installation. For a hinge that has 2 of the plates you would want the Polar Butt Hinge # PLR1005.

  • Option For Hinges For Trailer Ramp Door
    Appreciate the photo, and while I couldn't find any reference to part number I550-000, we do have a possible option for the ramp door hinge: - Ramp Door Hinge # PLR1902 The # PLR1902 has a pin that measures 8-3/16" long x 1" diameter and has a grease zerk like yours; the bracket measures 4" long x 2-5/8" wide x 1/4" thick so you can use those measurements to see if it will work for your application.

  • Does The Polar Hardware Ramp Door Hinge Come In Pairs Or As Single Units
    The Ramp Door Hinge - 8-3/16" Long - 1" Pin Diameter - Steel # PLR1902 comes as a single unit. Quantity of 1. So if you need two or more you will need to make sure you change the quantity bought to reflect the amount you need.

  • Replacement Ramp Door Hinge For 6 X 12 Enclosed Trailer
    Thanks For the photos of your hinges. That helps a lot when we are trying to find something for a customer. I have attached a photo of a hinge, part # PLR1902 that may work for you. You can check out the photo and see the dimensions for the hinge. The hinge measures 8-3/16 inches long, the end pieces are 1 inch in diameter, and the plate portion measures 4 inches wide by 2-5/8 inches deep. This hinge is made of steel and even has a grease fitting to keep it lubricated for smoother operation.

  • Replacement Ramp Hinges for Enclosed Trailer
    If your trailer is brand new and recently purchased ideally you would return to the dealer to have the ramp corrected. The amount of misalignment you describe seems excessive for a brand new trailer. If the trailer is parked on uneven ground the ramp may tend to lean to the low side; this happens just from the weight of the ramp twisting the hinge. If the ramp leans over even on flat ground then there may be damage to the hinges that secure it to the trailer structure or the ramp itself...

  • Replacement Ramp Hinge Recommendation for Trailer
    For a set of ramp hinges with a grease fitting the part # PLR1902 would work well for you. Overall the hinge measures 8-3/16 inches long, the end pieces are 1 inch in diameter, and the plate portion measures 4 inches wide by 2-5/8 inches deep. I attached a review video for this hinge for you to check out as well.

  • Hinge Recommendations for a 5 Foot Ramp to Support a 1,000 Pound Load
    The piano style hinges such as # SH200 are fairly stout but what I recommend is a combination of a piano hinge and regular ramp door hinges such as # PLR1902. Since you will be putting a considerable amount of weight on the ramp you want everything to be as strong as possible. The ramp is going to have to be pretty heavy to handle the weight so even though the hinge won't be bearing all the weight of the ramp and the bike it still has to handle the weight of the ramp opening and closing....

  • Ramp Door Hinges for Toy Hauler
    For your butt hinge, I recommend using the Paneloc 5 Knuckle Butt Hinge - 2-1/2" Long x 2-1/2" Wide - Stainless Steel # H674-200U. The pin diameter is 3/16 inch. You may want to use more than 5 depending on the weight you will be placing on that ramp door. For most toy haulers, a better option is to weld on the Polar Ramp Door Hinge - Steel # PLR1902, which has a built in grease zerk for easy maintenance. This is my recommendation for a stronger hinge for a ramp door.

  • What is the Weight Capacity of the Ramp Door Hinge - 8-3/16" Long - 1" Pin Diameter - Steel
    I checked with the manufacturer, Polar, about the Ramp Door Hinge part # PLR1902 and they unfortunately do not list a weight capacity as much of this would come down to how it's installed, the number used, and the quality of the welding. That said, it has a heavy duty 1/4" pin and it's designed for larger trailer ramp doors so if installed properly it can support a lot of weight.

  • Are Ramp Door Hinges for Trailer Available?

  • Recommended Ramp Hardware to Add Ramp to 2002 Sundowner Gooseneck Horse Trailer
    We do not have the Ramp you need, but we do have the hardware you would need to add a ramp to your 2002 Sundowner Gooseneck Horse Trailer. You will want a ramp door hinge like the Polar # PLR1902. You will weld the outside cylinders of the hinge to the trailer and the center section will be welded to the ramp you are adding. Another option is to use the 3" Wide Continuous Stainless Steel Hinge, 6' Long # SH300. To hold the ramp in place for travel, I recommend the 36" Lock Side-Door...

  • Hinge Recommendation to Make Fold Down Stage on Trailer

  • Ramp Hinge PLR1902 For Making Swing Out Trailer Barn Doors
    The Ramp Door Hinge # PLR1902 that you referenced could swing out as far as you are needing so it would work well for you. The slide door bar lock assembly part # 305736 can also be cut down as needed as well. Then for a mechanism to lock the door open you could use a rubber socket and plunger set like the part # PLR64-66.

  • Finding The Correct Ramp Door Hinge For A 2011 12' x 6' Mirage Cargo Trailer
    It is quite possible that the # PLR1902 hinge will be correct for your 2011 12x6 Mirage cargo trailer. These hinges are not custom fitted, so generally we like to get either measurements or pictures of the current hinge in order to recommend a replacement. That being said, this hinge is pretty much universal, and it is made for use with a ramp door. It is 8-2/16" long overall with a 4" long bracket. If you can measure out the current hinges this will tell us what will fit and what wont.

  • Recommended Hinges And Ramp Assist For Steel Ramp
    For your ramp, I recommend a hinge like the Ramp Door Hinge - Steel # PLR1902 or the Dump Door Hinge - Steel # PLR1904-Z. Both of these have a built in zerk grease fitting. Then you can use springs like # RS16933RH and # RS16933LH. If you want further help in lifting and lowering, I recommend the Rack'Em Double Barrel Utility Trailer Tailgate Lift Assist w/ Chain - 200 lbs # RA-27C that can be used on either side or both.

  • Availability Of Weldable Ramp Door Hinge Which Allows Ramp Door To Be Removed On a Utility Trailer
    The only ramp door type hinge we have that is weld on with a removable pin is the Aluminum # PLR1005. While the Ramp Door Hinge # PLR1902 you found does not have a removable pin you could weld it to a removable plate on the trailer which would then allow you to remove the entire ramp along with the hinges.

  • Do Any of the Continuous Hinges Have a Weight Capacity
    Polar doesn't have any weight ratings on their hinges, but if you alternated the use of a continuous hinge, like part # H300, and a Ramp Door Hinge, like part # PLR1902, it should work well under the 800 lb load you mentioned. I confirmed this with my contact at Polar . Attached is a list of our available door hinges for you to reference as well.

  • Availability of Rear Swing Down Door Hinge
    It sounds like you're looking for a hinge like the Ramp Door Hinge # PLR1902. This heavy-duty hinge replaces a damaged hinge on your trailer's ramp or access door. It has a steel construction and grease zerk fitting to easily grease it for easy operation. The bracket measures 4" long x 2-5/8" wide; x 1/4" thick and the pin is 8-3/16" long x 1" diameter.
