Em-D-Kay Padlocks MDKD30626 Dull Chrome 26D Double Cylinder Deadbolt door lock

Double-Cylinder Deadbolt for Keyed Entry

This Em-D-Kay MDKD30626 is a commercial-grade double-cylinder deadbolt finished in satin chrome. It requires a key to operate from both the exterior and interior sides of the door. The lock uses an SC4 keyway and ships with three keys, each cut differently for individual access control. It suits doors where keyed egress is required by code or preference.

Adjustable Latch Fits Common Backsets

The included latch adjusts between two standard backset measurements, allowing installation on a wider range of door preparations without extra parts. A dull chrome 26D finish resists wear in high-traffic environments. Heavy-duty construction meets commercial-grade durability expectations for frequent daily operation. The box contains the deadbolt body, adjustable latch assembly, and the three supplied keys.

Double Cylinder Demands Key on Both Sides

The defining specification is the double-cylinder mechanism: a key is mandatory to lock or unlock from inside as well as outside. This prevents thumb-turn bypass but also means occupants cannot exit quickly without the key in an emergency. Buyers who need a single-cylinder deadbolt with an interior thumb turn, or who require fire-code compliant egress hardware, should select a different lock type.
