Frommelt, a Milwaukee-based division of Rite-Hite Corp., introduced the Insulator dock seal with light-blocking header, designed to seal small light gaps caused byFrommelt insulator dock seal trailer protrusions. 

The seal at the top of a trailer provided by a dock seal header can be broken by door latches and other protrusions at the top rear of the trailer, resulting in air gaps. Insulator’s proprietary light-blocking header 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.

The design is also comprised of exclusive features that protect against extreme wear and tear, lengthening the life of the seal. For example, 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.

Plus, the Insulator’s corners are reinforced with layers of Durathon fabric and flexible high-molecular weight polyethylene sheeting for resistance to damage. 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 pivot to prevent yard jockey “pop-off.”
