AVCOM's Quick Release Rackmount Kit (QRM-35) allows the PSA-65C, PSA-37D, PSA-39A and PTR-25LCD to be installed in a standard 19" equipment rack. It is 7" in height. The front plate has 4 spring loaded thumbscrews for easy removal so that the PSA or PTR can be removed for use in the field and easily returned to the rack.
