Pass & Seymour WPEX1 – Frequently Asked Questions

1) Will the Pass & Seymour WPEX extension ring fit a standard one-gang weatherproof box?
Yes. The WPEX is a one-gang extension ring measuring 2.75 x 4.5 x 1 inches, sized to stack onto standard one-gang weatherproof boxes and covers. If your existing box is a two-gang weatherproof enclosure, this ring will not line up and you need a two-gang extension instead.
2) How much extra wiring volume does the WPEX extension ring add for box fill calculations?
It adds 9.5 cubic inches of interior volume on top of whatever the existing box provides. That is the number to use when you are running a box fill calculation and need more room for conductors, device yokes, or a weatherproof device assembly that won't fold back into the original box.
3) What's the difference between the WPEX1 and the WPEX4?
Hub count only. WPEX1 has one 1/2 inch hub; WPEX4 has four 1/2 inch hubs. Pick by how many conduit or cable entries you need to bring into the ring. If you are feeding through and continuing a run plus branching, the four-hub version saves you adding a separate body. Both are gray, one-gang, and carry the same 9.5 cubic inch capacity.
4) Is the WPEX extension ring approved for wet outdoor locations?
It's cULus Listed and built as a weatherproof component for outdoor and wet-location assemblies, which is what an inspector will look for on an exterior device box. Weatherproof performance depends on the whole assembly, so the cover and gasket you pair it with have to be rated for the same location.
5) I'm out of room in an outdoor box for a GFCI and a weatherproof cover. Is an extension ring the right fix or do I need a bigger box?
An extension ring is the quicker fix when the existing box is sound and properly mounted: the WPEX adds 1 inch of depth and 9.5 cubic inches, which is usually enough to get a deep device like a GFCI plus its conductors to sit back without crowding. Replacing the box only makes sense if the original is damaged, the raceway entries are wrong, or you need more than one gang, since the WPEX is one-gang only.
6) How many WPEX extension rings come in a box?
The WPEX ships 8 each per package. Worth knowing if you're ordering for a single repair versus stocking a service truck or standardizing hub entries across a run of exterior receptacles on a property.
7) Will the gray WPEX ring match the exterior boxes already on my building?
The WPEX comes in gray only, no other color offered. Gray is the common finish on exterior weatherproof boxes and covers, so it generally blends with what's already mounted. If your existing exterior hardware is bronze or white, the ring will stand out unless it's hidden behind the cover.
