CRL 6" x 10" Center Locks with Deadlatch (SKU: DL611LSDU) provide versatile security for commercial and office glass doors. These center-mounted deadlatch locks are available left- and right-handed and offer multiple long-tail options for specific applications: glass door center lock for 1/2 inch tempered glass, deadlatch center lock for commercial glass doors, and modular locks for frameless glass entrances. A simple cut-out in the glass is all that is required for installation — no messy cement or silicone — making these locks ideal for clean retrofit and new construction projects.
