Perimeter Door Sealing

Doors commonly develop small gaps between the door and frame along the:

• Strike jamb

Perimeter gasketing compresses against the closed door to help seal these gaps.

A properly fitted gasket can help reduce:

• Drafts

• Air leakage

• Dust

• Light penetration

• Noise

• Exterior debris

Commercial Applications

Designed for use with compatible:

• Hollow metal doors

• Commercial steel doors

• Commercial wood doors

• Storefront entry doors

• Single-door openings

• Paired-door openings

CDW currently positions this gasket for commercial steel and wood doors in offices, storefronts, warehouses, and industrial facilities.
