FSR PWB-323XL 3 in Extra Large Open Style Wall Box

Same box as the PWB-320XL, 1 in shallower. The 3 in depth is what makes it fit a thin wall or a wall with a stud cavity already crowded by conduit, and it is the version to specify when the 4 in box will not close.

Order the -Bx alone when the trim is coming from elsewhere, or the -TrK kit for the box plus its finished trim ring. The -SMK triple shelf kit adds three tiers of shelving with the side brackets to carry them.
