Designed for door openings up to 8’0’’ W * 8’0’’H where vehicles are of a generally standard size. Since the trailer is spotted before the seal  is inflated, the series F14/F18/F22  is the ideal solution to eliminate potential damage to the structure of a building wall. The unique sealing process seals effectively and completely even if the trailer is off center, jack knifed or on a sloped approach. The series F14/F18/F22 creates an optimum seal that blocks out foul weather, insects, dust, and dirt while saving money on energy costs. Inflatable dock door seals help productivity by increasing safety, protecting personnel; products, and equipment.
