Frommelt Products has released a new dock seal with light-blocking header that seals small light gaps commonly caused by trailer protrusions, the company said.

The Insulator Dock Seal’s design seals gaps caused by door latches and other protrusions at the top of the trailer that cause air gaps, allowing light, dust and bugs into a facility. Insulator’s proprietary light-blocking header design features rows of layered, horizontal pleats that conform around these protrusions as the trailer backs in, improving the sealing efficiency and minimizing the daylight that causes red flags during inspections, Frommelt said.

All trailer and forklift contact surfaces are reinforced with high-strength Durathon fabric over a flexible vinyl base fabric for extreme wear resistance. Durathon’s pebble-grained coating creates a friction-resistant surface that trailers slide against rather than abrade.

The Insulator’s corners are heavily reinforced with layers of Durathon fabric and flexible high-molecular weight polyethylene (HMWPE) sheeting for resistance to damage, and these components are attached with industrial Velcro for easy replacement and low-cost maintenance.

In addition, the Insulator head pad’s unique backerless construction frees it from the wall, allowing it to move with the trailer to reduce friction and wear, and also pivots to prevent yard jockey “pop-off.”
