Mul-T-Lock HD2-05-206 Double Cylinder Deadbolt

The Mul-T-Lock HD2-05-206 is a high-security double cylinder deadbolt designed for residential and commercial doors. It features a solid brass and steel construction with a bright brass finish. The lock uses the Interactive+ 206 keyway and includes a patented key control system with a key ID card. Two keys are supplied unless the cylinders are ordered keyed alike.

Adjustable Backset and Door Compatibility

Verify that your door thickness and bore hole dimensions suit a standard deadbolt installation. The adjustable backset fits recesses from 2 3/8 to 2 3/4 inches. As a double cylinder, it requires a key to operate from both the interior and exterior, so confirm this matches your egress requirements and local building codes.

Sustained Attack Resistance

The cylinder carries UL437 certification for drill and pick resistance and is UL listed for use on fire-rated doors. It meets ANSI Grade 1 standards for heavy-duty cycles and strength. The design protects against drill, wrench, ice pick, hammer, bumping and prying attacks over prolonged periods.

Questions about this item

What comes in the box with the Mul-T-Lock HD2-05-206 double cylinder deadbolt and what must be purchased separately?

The box includes the solid brass and steel deadbolt, an adjustable backset latch for 2 3/8 to 2 3/4 inch recesses, 5 keys (or fewer if keyed alike) and a key ID card. No extra parts are required for standard installation.

How do I choose between the 206 keyway and other keyways for this Hercular deadbolt?

The 206 keyway works with Mul-T-Lock's Interactive key control system. Select it when you need patent-protected key duplication control and compatibility with existing 206-profile cylinders in the same master-key suite.

What does the UL 437 rating mean for this deadbolt once installed on a fire door?

UL 437 certifies the cylinder resists drilling, picking and physical attack, while the UL fire-rated latch allows installation on labeled fire doors without voiding the door's fire protection listing.
