Fendock's DockStair is compatible with our Truss dock and Frame dock. Attractive, safe and durable, DOCKSTAIRS make it easy for anyone to enter and exit the water safely and in comfort. Our modular 2-STEP and 4-STEP stairs can be used independently or combined with our 2-STEP or 4-STEP Dockstair Extensions to create 6-STEP and 8-STEP configurations. DockStairs come with one handrail and a 5 1/2" stair tread. The rise is 9 inches on each stair, and the bottom step has a 24" adjustable leg.
