What are impact and dock protection doors?

Impact and dock protection doors are specialty door systems engineered for environments where forklifts, carts, pallet jacks, and high-traffic material handling equipment can damage standard doors. Barron Equipment supplies knock-out dock doors and impact traffic doors for warehouses, food processing plants, cold storage facilities, distribution centers, and retail operations throughout Iowa and the Midwest.

What is a knock-out dock door and how does it work?

A knock-out dock door is an insulated sectional door designed to flex and release from its track on forklift impact without sustaining panel damage. The PxV and MxV from DL Manufacturing use a patented polypropylene brush guide system instead of rollers. When struck, the panels release from the track and reset by simply opening and closing the door — no tools, no pins, no service call required.

What types of impact doors does Barron Equipment carry?

Barron Equipment carries knock-out dock doors and impact traffic doors. Knock-out dock doors include the PxV (1.75-inch steel panels, R-16 insulation, up to 10 feet wide by 10 feet high) and MxV (3-inch PVC panels, R-22 insulation, up to 10 feet wide by 12 feet high) from DL Manufacturing. Impact traffic doors include the Durulite Retailer Door (rotationally molded polyethylene, R-9.86, USDA compliant, NSF approved) and the AirGard, Compact Laminate, Lightweight Aluminum, Mega-Pro PVC, and Polar-Pro PVC series. All products are available by request for quote.

Which facilities use impact and dock protection doors?

These doors are used in warehouses, distribution centers, food processing plants, cold storage facilities, supermarkets, retail establishments, restaurants, institutions, and manufacturing facilities. Knock-out dock doors are preferred for high-throughput loading docks with frequent forklift traffic. The Durulite Retailer Door is USDA sanitation compliant and NSF approved for food service and food processing environments.

Impact & Dock Protection

Impact and dock protection doors are commercial and industrial door systems engineered for facilities where forklifts, pallet jacks, carts, and material handling equipment repeatedly impact door openings. Barron Equipment carries two classes of these systems: knock-out dock doors designed to flex and self-reset after forklift impacts at loading dock openings, and impact traffic doors designed for interior openings handling pedestrian, cart, and pallet jack traffic. All products are configured to your opening dimensions and are available by request for quote.

These door systems help reduce downtime, minimize maintenance costs, improve energy efficiency, and protect openings in warehouses, distribution centers, cold storage facilities, food processing plants, supermarkets, restaurants, and other high-traffic commercial environments.

Two Types of Impact-Resistant Doors — Which Is Right for Your Application?

Knock-Out Dock Doors

Knock-out dock doors are insulated sectional overhead doors designed for loading dock openings where forklifts and powered industrial vehicles are the primary traffic. The PxV and MxV models flex and self-reset after impact, helping eliminate door damage and expensive service calls at high-volume loading docks.

Impact Traffic Doors

Impact traffic doors are double-acting swing doors designed for interior openings where personnel, carts, pallet jacks, and equipment move through repeatedly. Products such as the Durulite Retailer Door are commonly used in walk-in coolers, food service operations, supermarkets, warehouse interiors, and industrial facilities.

Not sure which type is right for your facility? Barron Equipment can help evaluate your opening, traffic type, operating environment, and insulation requirements.

What Is a Knock-Out Dock Door?

A knock-out dock door is an insulated sectional loading dock door engineered to flex and release from its guide track when struck by a forklift or powered industrial vehicle, helping prevent panel damage and unplanned downtime. Instead of using traditional rollers, these doors utilize a patented polypropylene brush guide system that allows the door panels to release from the track and reset by simply opening and closing the door. No tools, replacement rollers, or service call are required after impact.

Benefits of Knock-Out Dock Doors

Reduces damage from forklift impacts
Helps eliminate door-related downtime
Self-correcting reset design
Continuous sealing performance
Improved long-term durability
Reduced maintenance requirements
Suitable for refrigerated and food-handling environments

Impact Traffic Doors for Interior Openings

Impact traffic doors provide a durable barrier while allowing frequent movement of personnel, carts, pallet jacks, and equipment through interior openings.

These doors are commonly used in:

Warehouses
Food processing facilities
Grocery stores
Retail back rooms
Restaurants
Walk-in coolers
Distribution centers
Institutional facilities

Unlike knock-out dock doors, impact traffic doors are intended for interior traffic flow rather than loading dock openings.
