Gatemaster Electric Striker | ERHDM (Electric Release Heavy Duty Morticed)

This heavy-duty electric release, equipped with an integral switch, can confirm whether a gate is closed. The ERHDM(Electric Release Heavy Duty Morticed) can be configured for either fail-safe (unlocking when power fails) or fail-secure (remaining locked during a power failure) operation, depending on your specific application needs.

The electric release is designed for durability, featuring a stainless steel faceplate and a deep locking tongue that provides greater tolerance for the gate. It is installed mortised into the gate frame. We recommend contacting a qualified electrician or an electric gate specialist for installation.
