Provide secure locking without projecting handles using the Adams Rite 4189 / 4190 Flush Locksets.

Designed for compatible aluminum and hollow-metal sliding doors, these all-metal flush locksets project only approximately 1/10" from either side of the door stile, allowing sliding panels to pass closely alongside adjacent stationary or sliding panels.

A deeply recessed finger pull provides convenient door operation, while the integrated Adams Rite deadlock mechanism uses an adjustable, self-protecting stainless-steel anti-lift bolt for commercial sliding-door security.

Choose the 4189 for interior slide-button operation without an exterior cylinder or the 4190 when keyed exterior access is required.

Low-Profile Sliding Door Design

One of the major advantages of the 4189 / 4190 Series is its extremely low profile.

The hardware projects only approximately:

1/10" from either side of the door stile

This allows the door to slide freely past:

• Adjacent sliding panels

• Stationary panels

• Other closely spaced door components

The low-profile design also makes these locksets particularly useful where sliding doors must stack into a wall pocket.

Interior Operation

Both the 4189 and 4190 are operated from the interior using a:

Vertical Slide Button

The slide button is recessed into the finger pull to minimize projection from the door face.

Moving the slide button:

• Projects the deadlock bolt

• Retracts the deadlock bolt

The deeply recessed pull also provides a convenient gripping point for manually opening or closing the sliding door.

4189 – Without Exterior Cylinder

Choose the:

Adams Rite 4189

when exterior keyed operation is not required.

The door is locked and unlocked using the interior slide button.

This configuration is useful for openings where:

• Exterior keyed access is unnecessary

• Interior control is preferred

• A flush exterior appearance is desired

4190 – With Exterior Cylinder

Choose the:

Adams Rite 4190

when keyed exterior access is required.

The 4190 includes a flush-mounted:

5-Pin Cylinder

with:

Schlage “C” Keyway

The exterior key can:

• Project the deadlock bolt

• Retract the deadlock bolt

Standard 4190 units are supplied:

Keyed Different – KD

and include:

2 Keys

Special keying options may be available through the factory.

Adjustable Anti-Lift Deadlock

The lockset uses an adjustable stainless-steel deadlock mechanism designed for sliding-door security.

The bolt provides an anti-lift function, helping resist attempts to:

• Pry the door from the jamb

• Lift the sliding panel

• Defeat the opening by vertical movement

The bolt reach is adjustable to accommodate installation and alignment requirements.

Self-Protecting Bolt

The deadlock mechanism incorporates a self-protecting bolt design.

This helps reduce the possibility of damaging the lock if the door is moved against the jamb while the bolt is improperly positioned.

Lock Face Options

Two lock-face configurations are available:

-09 Radius-End Lock Face

Specify:

-09

for a lock face with:

Radius Ends

-10 Square-End Lock Face

Specify:

-10

for a lock face with:

Square Ends

Always verify the existing door preparation before ordering.

Variable Backset

The 4189 / 4190 Series provides an adjustable installation range.

Minimum Backset

5/8"

Maximum Backset

1-9/32"

Backset is measured from the face of the lock to the centerline of the escutcheon and cylinder.

This variable arrangement provides flexibility when adapting the lockset to compatible sliding-door stile configurations.

Required Stile Depth

The minimum clear stile depth is:

Selected Backset + 9/16"

Verify the available internal stile depth before preparing or ordering the door.

Metal Escutcheons

The 4189 / 4190 Series uses:

Zinc-Alloy Escutcheons

with a:

Satin Silver Epoxy Finish

Both sides incorporate deeply recessed finger pulls while maintaining the low-profile design required for sliding doors.

No Latching Function

Important

The 4189 and 4190 are deadlock locksets, not spring-latching locksets.

There is:

No Latching Action

The bolt must be intentionally projected or retracted using the:

• Interior slide button

• Exterior key on the 4190

Do not specify these locksets where an automatically latching door is required.

4195 Dummy Set

For paired or matching sliding-door installations where a non-locking pull is required, Adams Rite offers the:

4195 Matching Dummy Set

The dummy set provides a matching appearance without the locking mechanism.

Optional 4413 Interior Pull

The:

Adams Rite 4413 Interior Pull

is available separately for compatible installations requiring additional pull hardware.
