great design, hasn't corroded yet, doesn't look like it will.



by:

Item was as expected and serves my purp ose



by:

Supposedly an adjustable lock but only works on the largest setting which means if you have something smaller it leaves it vulnerable to bolt cutters. Virtually worthless because of this

I like your honesty. It is a sad fact that any lock can be defeated if a person is determined enough. We consider the locks to be a theft deterrent against an easy theft.

See what our Experts say about this Blue Ox Trailer Coupler Locks

  • Should Curt Tri-Ball Trailer Coupler Lock C48CR Rust After 6 Weeks
    The Curt Tri-Ball Trailer Coupler Lock for 1-7/8", 2" and 2-5/16" Ball Couplers # C48CR should not be rusting after 6 weeks. The lock has an overall lifetime warranty from general defect, but a specific 1-year warrant for its finish. Clearly, this lock is not meeting those standards to I would warranty claim it. I would then go with something that won't corrode, the stainless steel Blue Ox Adjustable Trailer Coupler Lock # BLU56XR.

  • Replacement 1/4" Latch Pin For Buyers Products 50-Ton Pintle Hook # 337BP880
    It sounds like you are looking for the Buyers Products 1/4" Zinc Plated Safety Pin w/ Lanyard # 3373006875 to secure the pintle in place on the Buyers Products 50 Ton Heavy-Duty Swivel Type Pintle Hook # 337BP880. We do have the Coupler Lock # BLU56XR which will latch from 7/8" to 3-1/2" in length if you are looking for an actual locking pin.

  • Can Blue Ox Adjustable Trailer Coupler Lock Be Trimmed?
    If you want to trim off the excess part of the shaft for the Blue Ox Adjustable Trailer Coupler Lock # BLU56XR you are more than welcome to - I just recommend keeping at least one extra segment in place. Really the only reason to not trim it is for longevity sake. If you end up getting a trailer that requires that part of the lock to be longer then you'll need to purchase a new lock instead of being able to use this same lock. But the call is totally up to you! It is important to note...

  • Keyed Alike Coupler Lock Recommendation with 1/4 Diameter and at least 3-3/8 Span
    The Blue Ox Adjustable Trailer Coupler Lock # BLU56XR comes as individual lock numbers so for a keyed alike option I recommend checking out the etrailer Surge Brake Coupler Lock # e98888 which has the same specs but is only 1/8" shorter. The etrailer lock can be keyed alike no matter how many you choose to purchase. Attached is a review video for you to check out.
