Secure your fence or railing gate with the Keystone 1-sided gate latch. Manufactured from high quality, durable polymer the Keystone latch will not rust or corrode over time. The Keystone gate latch features a sophisticated, traditional design and provides superior reliability. The Keystone latch will work on vinyl, wood or metal gates, comes with 2 keys and is keyed alike, so if you purchase multiple latches the same key can be conveniently used on all of them. It can be rekeyed to match a 5 pin key, if you prefer to match the latch to your house key. The Keystone latch can be installed to accommodate either left or right swinging gates; see installation instructions for details. The Keystone latch comes with everything you need for installation, including instructions and all fasteners. The Keystone 1-sided Latch fits square gate posts up to 5 in. and requires a gate gap between 1/2 in. and 1-3/4 in. The Keystone Latch is compatible with single and double gates, but will require a drop rod (not included) with double gates. The Keystone Latch comes with a 1 million cycle warranty so you can feel confident it will stand the test of time.
