What the W28-3400 Does

The inside safety release is an important part of a commercial walk-in door assembly. When the interior release is activated, the push rod transfers force to the exterior latch mechanism so the walk-in door can be opened from the inside.

The recessed design positions the release knob inside a protective cup, helping reduce accidental impact and damage from equipment or product being moved inside the walk-in.

• Push rod is cracked, bent, or damaged
• Inside release knob is broken or missing
• Recessed cup or mounting flange is damaged
• Inside release no longer operates the exterior latch correctly
• Release mechanism sticks or does not move freely
• Walk-in door latch or safety hardware is being rebuilt

Commercial Applications

Before You Order

Confirm the W28-3400 part number, recessed mounting configuration, and 4-inch door thickness before ordering. Component Hardware manufactures W28 Series safety releases for different door thicknesses and mounting arrangements.
