Upgrade a mechanical storefront opening to electronic access control with the Adams Rite Steel Hawk® 4300 Electrified Deadlatch.

Designed specifically for narrow-stile aluminum entrance doors, the Steel Hawk 4300 fits standard Adams Rite MS® door preparations and can replace compatible MS® Deadlocks, 4500 Series Deadlatches, and 4900 Series Deadlatches without modifying the door stile.

The 4300 combines a heavy-duty stainless-steel latchbolt with 12, 16, or 24 VDC fail-secure operation, making it an excellent retrofit solution for card readers, keypads, access-control systems, and other electronically controlled commercial entrances.

Current Enhanced 4300 Design

Adams Rite enhanced the Steel Hawk 4300 platform in 2026 with a redesigned latch assembly and internal improvements.

The updated design is engineered to:

• Reduce opening force

• Improve latch operation

• Better accommodate door sag

• Improve performance on slightly misaligned openings

• Extend useful service life of existing storefront doors

• Maintain reliable access-control operation as openings age

This makes the Steel Hawk especially useful for retrofit installations where an existing aluminum storefront door may no longer be perfectly aligned.

Fail-Secure Operation

The Steel Hawk 4300 is available in:

Fail Secure Only

When Power Is Removed

The exterior side remains locked.

When Voltage Is Applied

The electrified mechanism allows the latchbolt to be retracted by the compatible exterior operating trim.

Interior egress remains mechanically available through the proper Adams Rite handle or paddle configuration.

Electrical Specifications

The 4300 is field selectable for:

• 12 VDC

• 16 VDC

• 24 VDC

Current Draw

12 VDC: Approximately 0.44A
16 VDC: Approximately 0.458A
24 VDC: Approximately 0.23A

Important 16V Note

A:

VA 7400-16VDC Adapter

is required when operating the lock from a 16 VDC source.

Duty

Continuous Duty

This allows the lock to be used with timed access-control applications without requiring momentary-only activation.

Access-Control Applications

The Steel Hawk 4300 can interface with compatible:

• Card readers

• Keypads

• Access-control panels

• Request-to-enter systems

• Time clocks

• Intercom systems

• Remote door-release controls

• Building security systems

Applying the proper voltage releases the electrified locking mechanism for controlled entry.

Interior Egress

The 4300 remains mechanically operable from the inside through compatible Adams Rite trim.

Available trim options include:

• 4560 Deadlatch Handle

• 4565 Deadlatch Handle

• 4568 Eurostyle Handle

• 4569 Eurostyle Handle

• 4590 Paddle

• 4591 Paddle

• 4600 Deadlatch Handle

This allows occupants to exit mechanically without relying on electrical power for normal egress.

Important 4600M Note

The:

4600M Handle with Monitoring Switch

cannot be used in conjunction with the Steel Hawk 4300.

If latch-status monitoring is required, specify the 4300M monitored lock configuration instead.

Optional 4300M Monitoring

The 4300M version adds an optional:

Form C Latch Status Monitor

This allows a compatible access-control or security system to monitor the position of the latch.

Possible uses include:

• Door-status reporting

• Security monitoring

• Access-control logic

• Alarm integration

• Building management integration

Stainless-Steel Latchbolt

The latchbolt measures approximately:

5/8" x 1"

with a:

5/8" Throw

The stainless-steel construction provides durability for frequent commercial use.

Auxiliary Deadlatch

An all-metal auxiliary bolt deadlocks the main latchbolt when the door is properly closed against the strike.

This helps prevent attempts to manipulate the latch using:

• Cards

• Knives

• Similar objects

commonly referred to as loiding or case-knife entry.

Backset Options

The Steel Hawk 4300 is available with:

• 31/32" Backset

• 1-1/8" Backset

• 1-1/2" Backset

Always match the new lock to the existing door preparation.

MS® Prep Retrofit

One of the biggest advantages of the 4300 is its compatibility with standard Adams Rite MS® Prep aluminum doors.

It can replace compatible existing:

• MS® Deadlocks

• 4500 Series Deadlatches

• 4900 Series Deadlatches

without cutting or drilling the door stile when the existing preparation is compatible.

This can substantially reduce installation time when converting an existing mechanical storefront opening to electronic access control.

Mortise Cylinder Compatibility

The lock accepts a standard:

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

equipped with an Adams Rite MS® cam.

Compatible examples include:

• Adams Rite 4036 Mortise Cylinder

depending on the desired opening configuration.

Cylinder and thumbturn are sold separately.

Faceplates

• Flat faceplate

• Radius faceplate

Faceplate Size

1" x 6-7/8"

The flat faceplate can also be adjusted in the field for compatible:

• Right-beveled doors

• Left-beveled doors

Strike Options

Select the strike that matches the frame and existing preparation.

4304 Surface-Mount Strike

Ideal for easy retrofit installations where minimizing frame modification is important.

4901-01 Mortised Flat Strike

where required for getting low-voltage wiring from the frame to the door.

Finish Options

Common faceplate finish options include:

• 628 – Clear Anodized Aluminum
