Mad River Seat Truss
Here's what other sites are saying:
Instead of 4 individual hangers suspending the seat, the truss is a one piece unit that provides increased stiffness, strength, and efficiency. 4"" Ash trusses are sold in pairs. They can be cut to fit specific applications and can be stained to match existing trim. One truss kit and 1 truss hardware kit is all that is needed to mount 1 canoe seat.
