The MagnaLatch Top Pull Safety Gate Latch, World's 1 Pool & Child Safety gate latch for over 30 years. The technology has been tested to over 2 million open/close cycles. Meets all international pool safety codes and is backed by a limited Lifetime Warranty. After the simple installation your security gate will be secure and children will not be able to reach the child resistant knob to open the latch and enter potentially unsafe areas. For an extra level of security you can lock the latch with the provided key, or re-key the lock cylinder to match existing doors. TruClose Regular hinges for fences and gates are adjustable, self-closing, and come in a variety of colors to match your material of choice or your existing backyard fence. The quick and easy tension adjustment can be used to adjust your hinges to the gate weight and the closing speed. Simply use a large screwdriver at either end of the hinge barrel. The gate gap spacer (for up to 2" gate gaps) is a valuable add-on for you to install with your MagnaLatch system to ensure a secure fit. The TruClose Hinge Safety Cap simply goes on the lower TruClose hinge and is a deterrent for children to climb on.
