Plastic Mounting Bracket with Thumbscrew – Used to secure seat tubes to mounting track or rails to rails. As found in Surge Fusion but will likely suit other brands
Suitable for kayaks where the metal and fabric raised seat is attached to the kayak via a track or rail system (so it can be adjusted for and aft). This mount uses the horizontal cross bar on the base of the kayak to slot into a recess in the mounting block and the mounting block is then secured to the track in the kayak
