Don't risk operational delays or cleanroom shutdown because of a damaged door! Terra's pass-through chambers last indefinitely, much longer than our standard product revision cycle. Pass-Through doors, however, are subject to damage, and ordering a legacy replacement can be costly and disrupt cleanroom operation. To avoid these problems, order replacements at the time you purchase the pass-through chamber; simply add "-RH" (for right-side hinge) or "-LH" (for left-side hinge) to the part number of the chamber.

(1) Mounting brackets, included, are made of stainless steel. All brackets require 0.25" (6 mm) clearance between wall cut-out and pass-through. Standard mounting is 2" (51 mm) from the front of the cleanroom side (specify other desired location). One set is welded on the cleanroom side. Floor Mount models include low-profile access ramps for easy transport of carts (subtract 1" (25 mm) from internal vertical clearance to compensate for ramps).
