B-LINE 8812 GRT NK – Frequently Asked Questions

1) Can the B-Line 8812 GRT NK wiring trough be used outdoors?
It's a NEMA 3R rated steel trough, so it's built for outdoor use where rain and falling debris are the concern, not washdown or dust-tight service. The screw cover seats against a flange and is held by plated screws, which is what maintains that 3R closure. For indoor wet washdown or dust-tight requirements you need a 4 or 12 rated enclosure instead.
2) What are the actual box dimensions of the B-Line 8812 GRT NK trough?
8 inches height, 8 inches width, and 12 inches length/depth. That 8 x 8 cross section is what you size against your conduit fill and bend radius; the 12 inch length is the run of the body itself, so longer runs are made by coupling multiple sections.
3) Does this 8x8x12 wiring trough come with knockouts already punched?
No. The 8812 GRT NK is the NK (no knockouts) version, so every conduit entry has to be field punched or hole-sawed where you want it. That's the version electricians pick when the conduit layout is non-standard or when they want full control over where the enclosure is penetrated. If you'd rather have factory knockouts, order the knockout version of the same size instead.
4) How does the cover come off for pulling wire, and does it need tools?
Screw cover. The full-length cover is retained by plated screws against a flange, so you back the screws out with a driver to open the whole face for pulling and lacing conductors. It's not a hinged or quarter-turn design, so plan for a screwdriver at every access point.
5) How do you mount the B-Line 8812 GRT NK trough to a wall or strut?
The back of the trough has embossed thru holes, so it bolts straight to a wall, backboard, or strut channel with your own fasteners. Mounting hardware is not part of the trough, so pick anchors rated for the substrate and for a unit that weighs about 9.573 lb empty plus the conductor load.
6) Is the B-Line 8812 GRT NK trough acceptable for a job in Canada?
It's CSA Certified, which is the listing Canadian inspectors look for. Combined with the NEMA 3R construction, it covers outdoor-rated raceway and pull box use on both sides of the border.
7) What gauge steel is the B-Line 8812 trough, and will the finish match my other gear?
16 gauge steel, finished in ANSI 61 gray, which is the standard gray used across most commercial switchgear and panel enclosures, so it blends with the rest of a typical electrical room lineup.
