Video Transcript for Redline Enclosed Trailer Parts - Doors - HP344G Review
Today were going to review part number HP344G. This is the Redline -inch diameter greasable hinge pin. This hinge pin is designed to be welded to either the outer from of the trailer or the gate and door of the trailer, and then it is inserted into a hinge pin nipple to create a custom heavy duty hinge. Greasable pins featured this grease zerk fitting on the end for lubrication. In other words, when you hook the grease gun up to the zerk fitting and pump in the grease, this hole here will allow it to come out and lubricate this section here which will be inserted into a hinge pin nipple. This part is great for building your own hinge.
Its also great for trailers in agriculture applications. A few measurements on this; the length is 4 inches, the base diameter is going to be 1 inch and the diameter that slides inside the hinge pin nipple is going to be 0.75 or of an inch. Now the part number for the hinge pin nipple that is normally used with this hinge pin would be HPN342 and that is this part right here which is sold separately. In other words, the hinge pin would insert right into this nipple and when you pump it with grease it would lubricate the connection. That should do it for review on part number HP344G..

The trailer door hinge lock works great. The only complaint I had was the ends don't fit the pipe very snug so i drilled and tapped some holes and added set screws.

I used this to repair a Haulmark ramp door hinge that the Haulmark factory had only tack welded to the frame. Welded to the existing door tab and welded the mating sleeve to the trailer frame and I am back in business. Works better than the original for smoothness

These ramp door hinges work great, a big upgrade from my original setup that couldn’t be lubricated and eventually rusted together

Going to use two of these for a heavy duty swing away tire carrier that I am making for my offroad buggy. I think that it will be plenty strong and like the serviceablity of the zerk.

Second time I have bought from these guys, and they are my go to supplier for these kind of parts. Easy to navigate the site, easy check out, and received in less than a week with just the standard option! Haven't had a chance to do the work yet, but product quality seems solid and well made. Highly recommend!

Product is exactly what i wanted and got to me in an ok time to. Would have gotten to me sooner if ups brought it to me but instead they transferred it to the post office which added an extra day.

See what our Experts say about this Redline Trailer Door Hinges
- 6 inch Long Trailer Hinge that is 3/4 inches in DiameterFor a 6 inch long hinge setup that has a 3/4 inch diameter you would want the part # HP34G and # HPN3342. These two pieces together will give you a hinge in the dimensions you requested.
view full answer... - Replacement Hinge Pins for Trailer GateIf you're looking for hinge pins like part # HP344G we carry several different sizes. Some greasable and some non-greasable. If you're looking for the style that is a solid hinge bar that extends across the entire trailer gate we do not have any of those.
view full answer... - Hinge Pin Socket to Use with part # HP344GYes the part # HP344G is only one part of the hinge. You would need the part # HPN342 for a 2 inch long socket or part # HPN34214 for 2-1/4 inch long.
view full answer... - Can the Polar Door Hinge PLR1902 be Separated?The ends of the Polar Ramp Door Hinge # PLR1902 are actually welded on, so they cannot be separated. However, we do have a few other options available for you. The Polar Dump Door Hinge # PLR1904-Z does use a bolt to hold everything together. There is still a zerk fitting to allow everything to be lubricated. It is quite a bit different, however, so the next option may be a better option. The Redline 3/4" Greasable Hinge # HP344G can be paired with # HPN342. This could then be adapted...
view full answer... - Weight Capacity of Redline HP344G Greasable HingesAccording to Redline, the # HP344G hinges don't carry a weight rating, but if Installed correctly, I can't see the hinges being the weak link. The strength of your ramp will be contingent on how it's constructed and the quality of the welds fastening the hinges to the trailer and tailgate.
