Oil & Dust Tight Wiring Box



Ralston’s PB35-BC series enclosures are designed to provide protection against dust, dirt and oil.



All PB35-BC enclosures are made from 14 ga. hot rolled steel and have continuously welded seams ground to a smooth finish. Each enclosure comes complete with grounding studs and wall mounting back brackets welded to the top and bottom outside.


PB35-BC doors are sealed with oil resistant neoprene gasket and are secured to sealed (blind) rivnuts in the enclosure with 10-32 captive screws.


Paint Finish

All enclosures are phosphatized and finished inside and out with ANSI/ASA 61 grey polyester powder coating.



PB35-BC enclosures are built to the requirements of NEMA Type 12 specifications for use with industrial controls in ordinary locations, and type 13 for an oil and dust tight enclosure.


PB35-BC enclosures are CSA certified (file #1174410) and UL 508 Listed (file #136838) as a type 12 enclosure.
