Recommended Trailer Coupler and Locks for Rollback Car Trailer with 3 Inch Tongue


My 7000# - 2 trailer coupler is a custom make on a rollback car trailer out of Texas .. It is welded to a 3inch x 3inch tube with a slide pin blocking the ball into the coupler ..The problem as I see it is that it has no lipfoot on the ball coupler.. What lock would you recommend for this situation ???... As a secondary question: I have considered doing an R and R on this unique coupler as it is partially non-functional tongue jack failed ... So recommend both a 2inch coupler and a tight fitting, super strong tongue lock as a total replacement ... THX for your timely attention this issue

The only 3 inch hitch lock we currently have is the Weigh Safe Hitch Receiver Lock for 2", 2-1/2", and 3" Hitches - 3-1/2" Span # WS05. This will secure your 3 inch x 3 inch receiver tube and accessory. For a jack, you can use the Round Snap Ring Swivel Jack w/ Footplate - Bolt On - Black - Topwind - 10-1/2" Travel - 2K # TJBB-2001-B.

If I undersand your issue, it sounds like you need the Titan Zinc-Plated Straight-Tongue Coupler - 21,000 lbs # T4853100 for a heavy-duty trailer coupler or the Fulton Fast-Lok Coupler - 2" Ball - 3" Channel - 6,000 lbs # F346000301. You can use the above lock to secure the coupler or you can use a weld on coupler like # BD028243 or # BD028444.

If you need a coupler lock, I recommend the Master Lock Heavy-Duty Coupler and Latch Lock Combo for 1-7/8", 2", 2-5/16" Couplers # 3784DAT. This will lock your coupler in 2 locations if needed. I've attached a video to assist.

Let me know if I misunderstood and you need another option.
