Mul-T-Lock Hercular Grade 1 High Security Double Cylinder Deadbolt (206 Keyway)

The Mul-T-Lock Hercular Grade 1 double cylinder deadbolt (MTL600, 206 keyway) needs a key on both sides. It is a good fit for doors with glass near the lock, gates and back doors. The telescopic pin-in-pin cylinders resist drilling, picking and bumping, and keys can only be copied by an authorized Mul-T-Lock dealer with your key card.

Why choose the Mul-T-Lock double cylinder deadbolt

• Grade 1 strength: heavy-duty housing and hardened bolt resist prying and wrenching.
• Key on both sides: no thumbturn to reach through broken glass.
• Key control: restricted 206 keys that hardware stores cannot copy.
• Fits standard doors: adjustable 2-3/8" or 2-3/4" backset (how to measure).

Safety note: check your local fire code before installing a double cylinder deadbolt on a door used as an exit from a home.

Delivery: most Mul-T-Lock locks ship in a few days; special finishes can take up to about 1-1/2 weeks.
