Overview

The Heavy-Duty Foot-Operated Floor Bolt Lock provides effortless, fast, and secure bottom locking for commercial glass doors, double entry doors, French doors, and patio gates. Designed for convenient step-down engagement, a gentle tap on the top plunger pin instantly drives the 12 mm solid stainless steel bolt downward into the floor with a 62 mm (2.44") drop stroke. Constructed from one-piece cast aluminum alloy with high-precision internal springs, it is available with an intuitive side thumbturn knob or a keyed lock cylinder to safeguard homes, retail stores, and commercial offices.
