The PSI-350AA Adjustable Header Inflatable dock seal is the ideal solution for sealing door openings up to 8′ wide X 11′ high servicing truck/trailers of variable heights. Inclined or declined approaches to the loading dock are easily accommodated since the 100% air filled side bags inflate, to form a seal against the rear of the truck/trailer, while the header inflates and seals the top of the truck/trailer. The PSI-350 is well suited for loading docks that service trucks/trailers of varying width, and heights.
