Proline 400i

Proline doors are designed for strength and durability in abusive applications. They provide visual separation, sound attenuation and thermal separation. The doors can be manufactured to fit virtually any size opening. The door is designed to comply with all USDA sanitation requirements and is insulated.


Door Panel

The 400i is constructed with a 1.5” thick composite wood core with foam inserts and either a .032” thick tempered aluminum alloy panel with a satin anodized finish or a full-length stainless steel panel on both sides.


Black powder-coated aluminum spine provides additional reinforcement to enhance the strength of the door.


Full perimeter replaceable gaskets are provided with the door and stand up to heavy traffic while providing a positive seal for thermal separation.


Patented v-cam hinging system has a 240° hinge that swings 120° in each direction, wide enough to allow the entire door and bumper to completely clear the opening.
