Sea-Dog Thumb Latch Windshield Latch, Black Nylon, 324180-1 (Pair)

The Sea-Dog 324180-1 is a Thumb Latch style windshield latch designed to secure boat windshield doors with a simple twist action. It is built from UV resistant black injection molded nylon, giving it long-term resistance to sun exposure, saltwater spray, and the vibration boats experience while underway. The twist-to-lock thumb design lets you open and close the windshield door quickly with one hand, while holding the door firmly shut so it does not rattle or work loose from engine vibration at cruising speed.

This latch measures 1-1/2 inches in total length, with a tab height of 11/16 inch, a tab thickness of 3/16 inch, and a tab lift of 1/16 inch measured from the bottom of the latch to the bottom of the tab. These dimensions determine how the latch engages its mating strike or frame, so they are worth checking against your existing hardware before ordering. The latch is finished in black to blend in with most windshield frame finishes and door trim.

Sea-Dog sells the 324180-1 as a pair, so both latches needed for a typical windshield door are included in one purchase. It is a direct fit replacement for the same Sea-Dog thumb latch already installed on many boats, making it a straightforward swap when an existing latch cracks, seizes up, or loses its twist action from age and UV exposure.
