Single Cylinder Deadbolt for Residential

The Mul-T-Lock HD1-26-206 Satin Chrome Single Cylinder Deadbolt provides high-security locking for both residential and commercial entry points. It features a keyed cylinder on the exterior and a thumb turn on the interior for convenient egress. The unit is constructed from solid brass and steel components for durability and strength.

Adjustable Backset and Door Compatibility

Verify that your door thickness and bore hole dimensions accept a standard deadbolt installation before ordering. The lock includes an adjustable backset designed to fit door recesses ranging from 2 3/8 inches to 2 3/4 inches. Confirm your existing door preparation matches this range to ensure proper fit and alignment of the latch mechanism.

Two Keys and Key Control ID Card Included

The package supplies two keys and a key ID card that supports the manufacturer's patented key control system, restricting unauthorized duplication. The cylinder carries UL437 certification for drill and pick resistance and is UL listed for use on fire-rated doors. The ANSI Grade 1 rating confirms heavy-duty performance against physical attack methods including bumping, drilling, and prying.

Questions about this item

Does the HD1-26-206 box include the strike plate and mounting screws, or must they be purchased separately?

The lock is sold as a complete unit in a box with two keys and a key ID card. The adjustable backset fits standard door preparations, so no extra parts are needed for a typical installation.

How do I decide between the 206 keyway and other Mul-T-Lock keyways for this deadbolt?

The 206 keyway is the specific interactive cylinder profile built into this model. It works only with matching Mul-T-Lock 206 keys and cannot be mixed with other keyway families.

What does the ANSI Grade 1 rating mean for daily security on my front door?

Grade 1 is the highest residential and commercial durability standard. Combined with UL 437 cylinder resistance and the adjustable backset, it certifies the lock against drilling, picking, bumping and forced entry.
