Provide heavy-duty mechanical security for compatible sliding doors with the Adams Rite 2331 Heavy Duty Deadbolt.

Designed for hollow metal and wood sliding-door applications, the 2331 uses a large brass deadbolt that projects into the strike and then expands two stainless-steel locking dogs above and below the main bolt.

This expanding-bolt design provides positive mechanical engagement inside the strike while allowing the complete lock to be operated with a single turn of the key or thumbturn.

Expanding Deadbolt Design

The 2331 operates differently from a conventional straight deadbolt.

When locked:

1. The main brass bolt projects horizontally into the strike.

2. Two stainless-steel dogs expand above and below the main bolt.

3. The expanded bolt assembly becomes mechanically captured within the strike.

This provides strong positive engagement for compatible sliding-door applications.

Main Bolt

The 2331 uses a brass main bolt measuring approximately:

1/2" x 1-1/2"

Horizontal Throw

3/4"

Once the main bolt is projected into the strike, the stainless-steel dogs expand to secure the lock.

Stainless-Steel Expansion Dogs

The two locking dogs expand:

11/32" above and below the main bolt

These dogs provide the secondary locking action that distinguishes the 2331 from a conventional sliding-door deadbolt.

360° Operation

A complete:

360° turn of the key or thumbturn

projects and expands the bolt or retracts and withdraws it.

The key cannot be removed unless the bolt is:

• Fully locked, or

• Completely retracted

This helps ensure the lock is positively positioned before the key is removed.

No Latch Action

The 2331 is a:

Deadbolt Only

There is no spring-latch function.

The lock must be manually projected or retracted using the appropriate cylinder or thumbturn.

1-3/4" Backset

The Adams Rite 2331 is available with one backset only:

1-3/4" Backset

Before ordering, carefully verify the door preparation.

The backset is measured from the front edge of the door to the centerline of the cylinder.

Sliding-Door Application

The 2331 is designed specifically for heavy-duty sliding-door applications including compatible:

• Hollow metal sliding doors

• Wood sliding doors

• Commercial sliding partitions

• Industrial sliding doors

• Institutional sliding openings

This is not the same application as the Adams Rite MS1850S straight-bolt lock typically used on swinging narrow-stile doors.

Mortise Cylinder Compatibility

The 2331 accepts a standard:

1" long x 1-5/32" diameter mortise cylinder

Adams Rite's current technical guidance specifies the 2331 uses a standard straight cylinder cam.

Compatible cylinder and thumbturn options may include:

• Adams Rite 4036 Mortise Cylinder

• Adams Rite 4066 Thumbturn

Always verify the required cam configuration with the selected cylinder before ordering.

The lock can accept operating hardware from:

• One side, or

• Both sides

depending on the desired door configuration.

Lock Case

The 2331 lock case measures approximately:

Width: 7/8"
Height: 3-5/8"
Depth: 2-5/8"

Case Material: Zinc Alloy

Verify adequate internal door clearance before preparing the opening.

Armored Faceplate

The brass armored faceplate measures approximately:

1" Wide x 5-3/4" High

The flat faceplate is available in multiple architectural finishes.

Strike

The 2331 includes a heavy-duty strike specifically designed to receive the expanding bolt.

Strike Dimensions

Thickness: 1/8"
Width: 1"
Length: 4-11/16"

Strike Opening

5/8" x 1-5/8"
