What is the standard thickness of a Compression Seal?

There is no standard thickness. The seal pads should compress from 4″ to 6″ – compressing the pad more than 6″ may over-compress the pads greatly reducing the useful life. The proper thickness depends on the thickness of the bumpers because the bumpers stop the truck. So, if the bumper is 6″ deep then the seal pad should be no more than 12″ deep. Similarly, if the dock door has an edge of dock leveler installed on it with bumpers projecting 16″, then the seal pad must project at least 20″ but no more than 22″.
