Product Definition

What Is a Stainless Steel Multi-Bolt Mortise Lock Body?

A stainless steel multi-bolt mortise lock body is a mechanical door locking component designed to be installed within a prepared cavity in the door edge.

It uses multiple bolt or latch elements to engage with compatible strike openings or receiving hardware in the door frame.

The lock body may be operated through a compatible handle, key cylinder or other designated mechanical control, depending on the internal mechanism.

The DEGOL ML1017 drawing shows an extended faceplate with several bolt elements, making it a multi-bolt mortise lock configuration rather than a simple single-latch lock body.

How Does a Multi-Bolt Mortise Lock Work?

When the operating mechanism is activated, the internal components control the movement of the relevant latch and bolt elements.

In a typical multi-bolt arrangement, one or more bolts extend into matching receiving positions in the door frame to secure the door.

When unlocked, the operating mechanism allows the relevant locking elements to retract or disengage.

The exact sequence depends on the specific lock's mechanism and must be verified for ML1017.

Multi-Bolt Lock vs. Single Deadbolt Lock

Important: Multi-bolt construction does not automatically establish a certified security grade or compatibility with fire-rated doors.
