Proline 600-SEC Postal-Security Door

Chase security doors are specifically designed and manufactured to be tough and dependable. They are strong enough to withstand punishing personnel-ridden vehicle traffic, yet lightweight enough to open easily, operate smoothly and allow for damage free, safe passage for personnel and equipment. All Chase security doors have been tested by the United States Postal Service and meet RE-5 security guidelines.

Door Panel – Proline doors can be custom manufactured to fit virtually any opening size. The panel’s outer surface is available with stainless steel, galvanized, aluminum or different color ABS face sheets. The core is constructed with a combination of wood and insulated foam.

Steel Spine – Steel spine reinforces the edge of the door against heavy impacts.

Gasketing – Full perimeter replaceable bulb gaskets are built into the ProLoc™ edge to stand up to heavy traffic while providing a positive seal for thermal separation. Partially gasket doors are optional.

Patented ProLoc™ Edge System – Chemically bonds to the face sheets providing a positive seal and preventing moisture or contaminates from entering the door panel.

Bumpers – The ultimate in door protection, the rotationally molded high-impact teardrop bumpers act as a shock absorber, extending the life of the door. 38" high bumpers are standard on both sides of the door.

Upper Hinge – Patented v-cam hinging system has a 250° hinge that swings 125° in each direction, wide enough to allow the entire door and bumper to completely clear the opening.

Lower Hinge Guard – Optional 9" high lower hinge guard protects the jamb and lower hinge from passing loads.

Window & Frames – Double pane windows include three security bars spaced on 7" centers making them virtually theft proof.

Additional Security – Upper and lower cane bolts, 2" chain or cable lock sleeves and tamper-proof fasteners are used for additional security.
