Complete or replace a commercial lock cylinder with the Hager 3902 Fixed Mortise Cylinder, configured with a 1-1/4" cylinder length, Schlage C keyway, keyed-different (KD) keying, and US26D Satin Chrome finish.

Machined from solid brass, the Hager 3902 is designed for dependable commercial door applications including compatible mortise locks, storefront hardware, exit-device trims, key switches, and other hardware accepting a standard threaded mortise cylinder.

This configuration uses a 6-pin cylinder body that is factory keyed as a 5-pin Schlage C cylinder.

Schlage C Keyway

The Schlage C keyway is one of the most widely used commercial keyways and is commonly found in:

• Commercial office buildings

• Retail facilities

• Warehouses

• Schools

• Healthcare facilities

• Government buildings

• Institutional properties

• Commercial storefronts

This makes the Hager 3902 a practical choice when matching or expanding an existing Schlage C key system.

KD – Keyed Different

KD (Keyed Different) means each cylinder is keyed individually rather than being keyed alike with other cylinders.

This configuration is useful when each opening requires its own unique operating key.

For projects requiring keyed alike, master keyed, or another keying configuration, verify availability before ordering.

1-1/4" Mortise Cylinder

This version features a 1-1/4" cylinder length.

Mortise-cylinder length is critical for proper installation. Before ordering, verify the thickness of the lock, trim, escutcheon, or door hardware where the cylinder will be installed.

Standard & Adams Rite Cams

The Hager 3902 is supplied with:

• Standard straight cam – installed

• Adams Rite cam – supplied loose in the box

This provides flexibility for use with multiple types of compatible commercial locking hardware.

Different hardware may require a different cam.

Important: Hager specifies a Schlage L cam when the 3902 is used with compatible Hager mortise locksets.

26D Satin Chrome Finish

The US26D / 626 Satin Chrome finish provides a clean commercial appearance that coordinates with many common satin-chrome and satin-stainless architectural hardware finishes.

Common Applications

• Commercial mortise locks

• Storefront deadlocks and deadlatches

• Exit-device trim

• Key switches

• Access-control hardware

• Electrified door controls

• Commercial security hardware

• Replacement lock cylinders
