Sea-Dog Snap Handle Drain Plug 1 Inch Brass, No Retention Chain, 520070-1

The Sea-Dog Snap Handle Drain Plug (520070-1) is a cam-action brass drain plug designed for a fast, leak-proof seal in boat transom and hull drain holes. Rather than threading the plug in and out, the snap handle design lets you simply turn the handle clockwise to tighten the plug against the drain hole, then snap the handle down flat to lock it in place. This cam mechanism speeds up launching and hauling out, since there is no repeated threading required once the plug is fitted.

Construction is durable stamped brass paired with a nitrile rubber seal, giving a corrosion-resistant plug with a reliable watertight gasket. This version of the 520070 series does not include a retention chain, so the plug is a standalone unit with no attached lanyard or tether. It is sized with a 1 inch drain hole diameter and a 1-1/4 inch overall body diameter, making it suited to boats built with a 1 inch transom drain fitting.
