    TB25KO fail-secure dropbolt with round strike hole

    The TB25KO high quality, high security drop bolt which includes a unique mechanical override in the event of power failure. Ideal for use on swing-through and double action doors, where an electric strike is impractical. Multiple orientation, drop bolts will work horizontally or vertically. Designed to be tamper proof and can’t be defeated by slipping a metal object between lock and strike plate.
