About This Product
The CURT 16050 is a puck adapter for trucks with factory fifth wheel prep packages. It converts your pucks to standard rails that accept any CURT fifth wheel legs and rollers. Rated at 30,000 pounds gross trailer weight with 7,500 pounds pin weight capacity.
This is the heavy-duty option for towing the largest fifth wheel trailers. The 30,000-pound rating handles big RVs, horse trailers, and commercial equipment without breaking a sweat.
The quarter-turn anchoring system makes installation quick and easy. Drop the adapter into your bed pucks and twist each anchor to lock it in place. The adjustable anchors eliminate play between the adapter and truck for a tight, rattle-free fit.
CURT uses a dual-layer finish with Aquence rust-resistant coating underneath a carbide black powder coat. The adapter is tested to SAE J2638 safety standards and backed by a limited lifetime warranty.
