Roller bunks make loading and unloading small craft at very short or even dry rams easy. Great for ramps where it is not practical to float the boat onto the trailer. Pre-assembled and pre-drilled for easy installation. Maybe be installed using mounting brackets if lift and/or angle is needed, or may be bolted directly to trailer frame for a flat bottom boat, or even mounted on top of existing bunk boards.
Durable 2 polypropylene rollers on 1/2 shafts mounted in a heavy gauge pre-galvanized channel
