Sea-Dog Hatch Adjuster 321295-1, Twist Lock Stainless Steel and Nylon, 11-15/16 to 17-7/8 Inch

The Sea-Dog Hatch Adjuster 321295-1 is a twist-lock support arm used to hold hatches, dock box lids, and windshields open at a set position. A simple twist of the knob locks the adjuster in place, holding the lid or panel securely until it is twisted again for release. The arm is constructed of formed 304 stainless steel for corrosion resistance in the marine environment, paired with UV resistant injection molded nylon mounting pads and a nylon knob that stand up to prolonged sun exposure without becoming brittle.

The adjuster spans 11-15/16 inches to 17-7/8 inches, with mounting pad dimensions of 1-3/8 inches and 1-3/16 inches, making it suited to mid-size hatch, dock box, and windshield applications. It installs with four fasteners, which are not included, attaching one pad to the fixed surface and the other to the moving lid or panel. Once mounted, the twist knob allows the hatch or lid to be propped at any point along its arc of travel and held firmly without drifting shut.
