Clearance Bars and Overhead Door Warning Barriers for Height Restriction Protection

Clearance bars, also known as overhead door warning barriers, overhead clearance bars, height restriction bars, and vehicle warning bars, provide a simple and highly visible method for alerting drivers to low-clearance openings before impact occurs. Ideal for loading docks, parking garages, warehouse entrances, drive-through lanes, canopies, and construction sites, these suspended warning devices help reduce damage to overhead doors, building structures, equipment, and vehicles. Their bright appearance and prominent positioning create an effective visual warning that promotes safer traffic flow in areas with height restrictions.

Key Features & Benefits

Manufactured from durable low-density polyethylene (LDPE), these clearance warning bars are designed to withstand a wide range of environmental conditions while requiring minimal maintenance. Each unit includes installed eye hooks for easy suspension using customer-supplied chain or cable. High-contrast lettering enhances visibility and improves driver awareness, while the lightweight construction simplifies installation and repositioning. The standard yellow finish is easily recognized in industrial and commercial environments, helping facilities improve safety and reduce costly collisions.

Applications

These overhead warning barriers are commonly used wherever vehicle height limitations must be clearly communicated. They are an excellent solution for warehouses, distribution centers, truck loading areas, parking structures, storage facilities, and commercial properties where protecting doors, overhead equipment, and building infrastructure is critical. This product requires minimal maintenance and is brightly colored for enhanced visibility. Models CLB-5-78L and CLB-7-110L are customizable up to 15 character spaces (spaces include: spaces, dashes, and/or feet, inches symbols). When no specifications are provided, models CLB-5-78L and CLB-7-110L will read "CLEARANCE". Lettering clearly contrasts with the color of the bar to be easily seen by motorists.
