Product Overview
Marine High-Strength Nylon Mountain-Shaped Seat & Mountain-Arc Seat
RICHWITS ZB1413 series gives you the strength of metal—without the weight, noise or price.
Injection-moulded from UV-stabilised PA66 + 30 % glass fibre, these “mountain” profile seats distribute 150 kgf (330 lb) across 60 mm of webbing or tube while weighing only 22 g.
Perfect for canvas tensioners, lazy-jack blocks, flag-pole bases, dodger arches or any deck hardware that needs a radiused, non-marring saddle.
