Commercial Double Cylinder Deadbolts

About

Shop commercial double cylinder deadbolts for controlled-access and other applications where the selected door configuration permits keyed operation from both sides. The assortment includes Grade 1 and Grade 2 models, conventional-cylinder and small-format interchangeable-core preparations, and deadbolts from several commercial hardware brands. Because a double cylinder deadbolt requires a key for operation on both sides, it can affect emergency egress and may be restricted by building, fire, life-safety, or local code requirements. Confirm that this function is permitted for the specific opening before ordering, then verify backset, door thickness, bore preparation, keyway or core format, bolt, strike, trim, and grade.
