Description

If you are replacing a broken coupler on your trailer or installing a new one on a trailer you are building, CURT has dependable couplers you can trust to keep your tow load latched on tightly. Selecting the right trailer hitch, ball mount and trailer ball to manage the weight of your trailer is not the only important aspect of towing; you also need a trailer that can stand up to the road ahead. That means equipping it with a coupler that is built to go the distance. CURT straight-tongue couplers, featuring our Posi-Lock latch, are the most common type of trailer coupler. With a mounting channel designed to fit onto a straight trailer tongue, the Posi-Lock coupler is easy to install. It is made from hardy steel construction and has a durable zinc finish to protect from corrosion, wear and tear. The lockable latch mechanism on CURT Posi-Lock couplers is easy to operate and adjusts by tightening or loosening a simple bolt. This CURT straight-tongue coupler features a gross trailer weight capacity of 5,000 lbs. and a tongue weight capacity of 700 lbs. It has a 3" channel and fits a 2" diameter trailer ball. All CURT couplers include a limited lifetime warranty and feature a lockable latch to give you peace of mind.

  • Fit perfectly?
Good quality

  • Easy install
Replacement for a 2001 boat trailer tongue. Very easy to install.

  • Very solid trailer coupler replacement
We bought this to replace the trailer coupler that came with our used boat, and which wasn't gripping trailer balls reliably. This is extremely solidly built and fit perfectly, and seems to be working well.

  • Good product for the money
Solid product no issues after much use this summer

  • Works perfect
Love the retention of the pin. Bought a second one after accidentally breaking the first with my tractor forks swiping the latch assembly. It held up well considering how I hit it but needed to replace it anyway.

  • It's worth it. It's worth it.
Coupler is very well made, sidewalls cover all 3 inches of trailer tung. The only complaint is the decal that will leave the paper stuck to it. Glad I've got plenty of acetone.

  • Good quality as advertised.
As advertised. I replaced the tongue on my tandem trailer and this bolted right up. I added another bolt through the middle for overbuild. Works perfectly.
