Commercial Storefront Deadlatch Strike | Narrow Stile Door Hardware | Replacement Security Strike

Complete or repair a commercial storefront locking system with this Single Dead Latch Strike, designed to provide a secure engagement point for compatible narrow-stile mortise deadlatches.

Mounted in the strike jamb of the frame, the plate receives the deadlatch bolt when the door closes, helping provide reliable latching and secure door operation.

Ideal for aluminum storefront doors, commercial entrances, and narrow-stile mortise lock applications, this replacement strike is an excellent choice for service, retrofit, and new-installation projects.

Single-Opening Strike Design

The single strike uses one primary opening for the deadlatch bolt.

This configuration is commonly used on storefront frames already prepared specifically for a deadlatch rather than an elongated or double-opening strike.

Commercial single-hole deadlatch strikes are designed for use with narrow-stile mortise deadlatches from multiple manufacturers.

Commercial Storefront Application

This style of strike is commonly used with:

• Aluminum storefront doors

• Narrow-stile commercial doors

• Mortise deadlatches

• Commercial entrance doors

• Retail storefronts

• Glass-and-aluminum entrance systems

The strike installs into the frame opposite the deadlatch so the latchbolt can engage securely when the door closes.

Deadlatch Security

A properly installed strike is an important part of the complete deadlatch system.

Correct alignment helps:

• Ensure positive latching

• Reduce latch binding

• Maintain reliable locking

• Improve door security

• Reduce unnecessary wear on the latchbolt

• Prevent the door from bouncing back open

Single Strike vs. Double Strike

Single Deadlatch Strike

Designed for frames with a dedicated single deadlatch opening.

Double Strike

Uses a longer plate with an enlarged or additional opening and is commonly used when converting an existing narrow-stile deadlock preparation to a deadlatch or when an elongated frame cutout must be covered.

Always match the strike to the existing frame preparation.
