ABSTRACT:
A dock seal for use around a building doorway against which any of various style trucks can back to create a totally-sealed, safe, dry passageway. It includes several sections around the building doorway each having a sealing body of resiliently flexible and compressible foam material of L-shaped cross-section enclosed in a thin flexible cover. The sections are so arranged that as the truck backs into cooperation with the doorway, a part of its rear edge engages the flexible flange of each seal section so that an effective seal will be created around the truck. This also creates a totally safe dry passageway for loading or unloading. The seal body cover is provided with ventilating means to facilitate compression, bending and expansion of the body and stiffening means where needed. Means is also provided for mounting the seal body for ready removal and replacement.
