SDC’s 55 series 3/4” latchbolt electric strikes are heavy duty, designed for installation in hollow metal frames for access control of cylindrical locksets, mortise locksets with or without deadbolts and mortise exit devices. 55 series strikes accept 3/4” throw latchbolts and up to 1” throw deadbolts.

The choice of six application faceplates eliminates the need for centerline relocation, making them ideal for new or retrofit, high security access control applications.

55 series strikes retrofit existing ANSI 47/8” strike prep – no centerline relocation required.

    Upgrade Your Security

    Posted by George on Feb 8th 2024

    I just wanted to share my thoughts on the SDC 55 D/E/F Series Electric Strikes. These bad boys are heavy-duty and offer top-notch security for my doors. I love the deadbolt feature for added protection. However, installation can be a bit complex, so make sure you have some DIY skills or a professional handy. Overall, worth it for the peace of mind they provide!
