Brass Single Cylinder Deadbolt

The Mul-T-Lock HD1-05-206 is a high-security deadbolt crafted from solid brass and steel. It features a single keyed cylinder on the exterior and a thumb turn on the interior for convenient egress. The lock carries a polished brass finish and includes two keys plus a key ID card for controlled duplication.

Suits Standard Residential and Commercial Doors

This deadbolt fits doors with an adjustable backset ranging from 2 3/8 to 2 3/4 inches. It meets ANSI Grade 1 standards and is UL listed for fire door applications. Buyers who need a double-cylinder configuration or a different finish should look at other models.

Interactive+ 206 Keyway with Patented Key Control

The cylinder uses the Interactive+ system with a 206 keyway, providing a double locking mechanism that resists picking, drilling, and bumping. Key duplication requires presentation of the included ID card to an authorized dealer using a specialized key cutting machine.
