B-Line Eaton series wiring trough, 8" height, 48" length, 8" width, GTGV NK wiring trough, Thru holes, No knockouts, Screw cover, 1, Galvanized steel

No knockouts. The GTGV NK trough ships as blank galvanized steel on all sides, so every conduit entry gets field punched exactly where your run lands. Order a knockout punch set for the conduit sizes you need; if you would rather have factory openings, specify a knockout version instead of the NK.

No. It is a NEMA 1 enclosure, which is indoor, dry location only, intended to guard against incidental contact with the enclosed wiring and falling dirt. For an exterior wall, a rooftop, or a washdown area you need a NEMA 3R or NEMA 4 gutter with a gasketed, hinged or clamped cover instead.

Mounting is through holes in the body, so it bolts directly to a wall, to strut, or to a backboard using your own fasteners. No mounting hardware, brackets, or strut clips come with it. Weight is 31.238 lb empty, so a one man wall hang is workable but plan your anchors for the filled weight once conductors are in.

If what is coming out is an 8 x 8 inch, 48 inch long screw cover NEMA 1 steel gutter, the 8848 GTGV NK matches on all of those. The two things to check on the old one before you pull it: whether the existing conduit entries were factory knockouts, because this one is blank and you will field punch every opening, and whether the old unit was mounted through the back panel, since this one mounts with thru holes.

It is a screw cover. The full length cover is held on with plated screws, so it lifts off completely once the screws are out, giving you open access down the whole 48 inch run for laying in conductors. It is slower to open than a hinged cover, which matters if you expect to be back in the gutter often.

The body is 14 gauge galvanized steel finished gray. The zinc coating handles the damp, condensing air you get in an unheated warehouse, mechanical room, or garage far better than painted carbon steel, and 14 gauge is stiff enough that a 48 inch section will not oil can when you bolt it up. It is still a NEMA 1 enclosure though, so it should not sit where it takes direct water or hose down.

It carries CSA C22.2 certification, so it is acceptable for Canadian installations under the Canadian Electrical Code as well as US work. Give the inspector the model designation 8848 GTGV NK and the CSA marking on the body.

Yes, sections of the same 8 x 8 inch gutter line up end to end because the cross section matches, and you cut the coupling openings yourself since the body ships with no knockouts. What you order separately is the connector and closure hardware, plus any elbow or tee fitting for a change of direction. Keep every joined section the same 8 x 8 size so the bolt pattern and wire fill stay continuous.
