DEADLOCK - DOUBLE DEADBOLT

A double cylinder deadbolt in a classic polished brass finish -- the go-to security upgrade for property managers, building superintendents, and contractors securing entry doors across residential and commercial properties. Unlike single cylinder deadbolts, the double cylinder design requires a key to operate the lock from both the interior and exterior, providing an additional layer of protection against unauthorized entry through glass panels, sidelites, or doors with nearby windows. Adjustable backset fits the two most common door preparations, and the reversible design suits both left- and right-hand door installations.

Key Features:

• Double Cylinder -- Keyed Both Sides: Requires a key to lock and unlock from both the interior and exterior -- eliminating the ability to reach through a broken glass panel, sidelite, or adjacent window to turn a thumb turn and gain entry. The preferred deadbolt configuration for glass-door and glass-adjacent door applications.
• Polished Brass Finish: Classic polished brass finish complements a wide range of door hardware and architectural styles in residential, multi-unit, and commercial building applications -- a timeless, professional appearance that holds up to regular use.
• Adjustable Backset: Fits both 2-3/8" and 2-3/4" backset door preparations -- the two most common configurations in residential and commercial construction -- for straightforward installation without special modifications.
• Reversible for Left & Right Hand Doors: Universal design installs on both left-hand and right-hand swing doors without additional hardware, making it a practical stocking item for property managers and contractors handling mixed door configurations.

Where to Use:

• Multi-Unit Residential Buildings: The standard security upgrade for apartment entry doors with glass panels, sidelites, or windows near the door frame -- where a thumb turn deadbolt would present a vulnerability.
• Commercial & Retail Storefronts: Provides maximum access control on glass-adjacent commercial entry doors where interior thumb turn operation would compromise security after hours.
• Property & Building Management: A reliable stocking item for building superintendents and maintenance teams handling door hardware repairs, unit turnovers, and security upgrades across managed residential and commercial properties.
• Contractor & Renovation Use: Adjustable backset and reversible design suit new construction and renovation applications across a wide range of door types and configurations.
