Dock Seal Fabric Performance Specification

Our full range of selected quality fabrics; Vinyl, "High Tear Resistant Guardian 60" and other optional fabrics, in a variety of colors and available fabric weights, make durable seals and shelters. The dock seal/shelter lifespan depends on the application; lighter duty fabrics have a lower investment cost and are best suited for low volume truck applications.

The Guardian 60, is the most durable and abrasion resistant fabric, it will endure the most demanding applications at the loading dock. Durability of the dock seal will be enhanced if it includes one of the following; wear face, guardian face, guardian pleats. For color selection we recommend black and most loading dock professionals do agree, that is the best color choice due to the contact of dirt, grime and oil on the back over-the-road trucks/trailers and contact with a dock seal/shelter, eventually the face of any dock fabric will turn black.
