Vertical pads are manufactured using kiln-dried pressurized wood, and a high density, light weight urethane foam core with 98% compression recovery and maintaining flexibility at -40° (fire retardant formula available). The foam core shall be continuously bonded (not spot glued) to the wood backing with a high quality, non-flammable elastic adhesive. Cover fabric shall be double stitched with high strength twisted 4 ply 100% polyester bonded thread U.V. treated. The cover fabric overlaps the wood backing totally enclosing it and is fastened with heavy duty plated staples.
Vertical pads are vented through brass plated grommets allowing air to be exhausted and moisture to drain. Vertical pads are tapered cut at the bottom to prevent sagging, pinching, wearing when compressed and tapered cut at the top to provide adequate drainage. Vertical pads have a full height 4″ yellow guide stripe to aid in spotting trailers. The adjustable head pad shall be equipped with self-lubricating steel rollers that glide up and down in a formed heavy duty galvanized steel track. An integral follower curtain shall be supplied to maintain a weather-tight environmental seal.
The head pad is lowered against the trailer by means of 2 pull chains. The header automatically raises to the up position once released. A galvanized steel header assembly cover is provided to enclose the roller and torsion spring assembly. Unit shall be furnished with all necessary mounting hardware, galvanized to resist corrosion.
