    Deadbolt for thick gates

    Posted by Jimmy on Jul 8th 2020

    While the extension for the bolt actuator is very functional, the tiny hex screw to secure it is a bit fussy to tighten. As a suggestion, I would like to see added to the square bezel around the keyed side of the lock a small set pin in each corner in order to keep it from moving or spinning over time. This could be knocked out for those gates not made of softwoods such as the redwood my gate is constructed out of. Also, the instructions call for a 2 1/8 hole to be bored which is FAR too large and way more than needed. I bored a clean, straight 1 1/4 inch hole through the gate and everything fits perfectly (1-inch for the deadbolt exit) ! , I heavily customized both the deadbolt exit point as well as the strike plate using thick gauge stainless steel plates to increase security. Other than the suggestions to the manufacturers/distributors above, I find the overall execution of this mechanism to be a viable and useful solution for those thicker, customized gates where a deadbolt is desired.
