Secure your fence or railing gate with the Trident 20 in. safety pool gate latch. Manufactured from high quality, durable polymer the Trident latch will not rust or corrode over time. The Trident gate latch features a sophisticated, modern design and provides superior functionality. It will work on vinyl, wood or metal gates and meets all international pool codes. The Trident gate latch comes with 2 keys and is keyed alike so that if you purchase multiple latches, they will conveniently all use the same key. The Trident gate latch features a top pull design for added safety so that children cannot reach the latch to open it. The Trident gate latch can be installed for left or right swinging gates; see installation instructions for details. The Trident latch requires a gate gap between 3/8 in. and 1-1/2 in. and can be used with square gate posts and gate frames. Gates with round posts require the Round Post Adapter (sold separately: ZBGA-LATCHRNDADPT-NW). The Trident latch carries a warranty to 1 million cycles, so you can rest assured it will stand the test of time.
