01 / OVERVIEW

Overview

The DG34 Intruder Dead Bolt Lock meets ANSI/BHMA A156.13 requirements and Grade 1 performance for heavy-duty use. Its cycle performance exceeds the Grade 1 requirement for doors subject to frequent operation.

The lock case and internal components are made of stainless steel, providing resistance to corrosion and wear. The heavy-duty construction is suited to applications requiring a high level of physical security.

The DG34 features cylinders on both sides, allowing the deadbolt to be operated by key from either side of the door. Both levers remain operable, allowing the latchbolt to be retracted while the deadbolt provides the primary locking function.

The DG Series uses a common multifunction mortise lock body that supports 10 functions and fits multiple door thicknesses and both wood and metal doors.

UL listed for up to 3-hour fire-rated openings, the DG34 is suitable for commercial buildings, institutional facilities, controlled-access areas, and other applications requiring enhanced security.
