CRL 6" x 10" Center Locks with Deadlatch (SKU: DL611LSPB) deliver versatile security for heavy glass doors. Designed for 1/2" (12 mm) tempered glass, these center locks require only a simple glass cut-out for installation and are offered in multiple finishes to match commercial and architectural interiors. Key differentiators: five distinct lock functions, quick shipping, tool-friendly installation without cement or silicone, and optional jamb-mount strikes for retrofit applications.

Storeroom Lock: Latchbolt operated by inside lever and by key outside; outside lever is fixed. Auxiliary latchbolt deadlocks the main latchbolt to prevent jimmying. Commonly used with electric strikes. Inside lever always allows exiting.

Classroom Lock: Latchbolt operated by lever on either side except when outside lever is locked by key outside. Key operates latch and unlocks outside lever; inside lever always operable.
