Frequently Asked Questions
Are these boxes NEMA 3R or NEMA 4?
NEMA 3R — rated for outdoor wet locations including rain, sleet, snow, and external ice formation. NEMA 4 (water-tight, hose-down) requires a different gasket configuration; if you need NEMA 4 specifically, contact us for the appropriate variant.
Do unused hubs need plugs?
Yes, NEC 314.17(B) requires unused hubs to be plugged. Each box ships with closure plugs sized to match the hub openings — no separate purchase needed.
Can I mix trade sizes on one order?
Absolutely — order any combination of 1/2", 3/4", and 1" boxes in a single shipment. Bulk pricing is calculated on total quantity across all SKUs.
What's the depth difference between standard and deep?
Standard boxes provide ~12 cubic inches of wire-fill capacity, sufficient for most single-device applications. Deep boxes provide ~21 cubic inches for situations with heavier conductors, more conductors, or internal device-mounted components.
Are these compatible with standard device covers?
Yes — these accept standard 1-gang weatherproof covers (in-use covers, GFCI receptacle covers, switch covers, blank covers). Cover not included; we sell those separately.
Do you offer larger sizes?
For 2-gang, 3-gang, or larger trade sizes (1-1/4", 1-1/2", 2"), contact us for a quote — we source those by request and typically ship within 1–3 business days.
