Product Identity

The Mul-T-Lock HD2-26-206 is a satin chrome double cylinder deadbolt designed for high-security residential and commercial doors. It operates with a key on both sides and features an adjustable backset to fit standard door preparations. The lock carries ANSI Grade 1 certification and UL437 cylinder rating.

Suitability

This deadbolt suits property owners who require keyed entry from both the interior and exterior for controlled access. It is not intended for doors where single-cylinder operation or thumb-turn egress is preferred or required by local code. Buyers needing electronic access or smart-home integration should consider alternative lock types.

Sustained Security

The solid brass and steel construction resists drill, pick, bump, wrench and prying attacks over prolonged exposure. UL fire-rated latch components maintain integrity during fire-door testing. Patented key control with the included ID card prevents unauthorised duplication throughout the lock's service life.

Questions about this item

Does the HD2-26-206 fit my door's existing backset?

The adjustable backset covers 2-3/8" to 2-3/4" recesses, so it fits standard residential and commercial door preparations without modification.

Will the 206 keyway work with my current Mul-T-Lock keys?

The 206 keyway is specific to this cylinder; existing Mul-T-Lock keys with a different keyway will not operate it, but the lock includes two new keys and a key ID card.

How do I confirm the deadbolt meets the claimed drill and pick resistance after installation?

The cylinder carries a UL437 listing, which independently verifies drill and pick resistance; the UL mark on the cylinder face confirms compliance.
