B-Line Eaton series wiring trough, 10" height, 12" length, 10" width, HS wireway, Thru holes, 3 top knockouts, 3 bottom knockouts, Hinged cover, 1, S

It's a 10 x 10 x 12 inch trough: 10 inch height, 10 inch width, and 12 inch length/depth. That 10 by 10 cross section is the wireway gutter size, and the 12 inch run is a short section typically used as a pull box or junction point between longer trough runs rather than as a main horizontal run. Shipping weight is 8.602 lb.

No. The 101012 HS trough is a NEMA 1 enclosure, which is indoor, general purpose only. It gives you protection against incidental contact with the enclosed conductors and falling dirt, with no gasketing against rain, washdown, or dust. For an outdoor run or a wet mechanical room you need a NEMA 3R or NEMA 4 gasketed wireway instead.

It's a hinged cover, so it swings open and stays with the body when you're pulling or landing conductors. The cover is secured to the body with plated screws, so you back those out and swing it rather than lifting a loose lid off a live gutter. That's the practical difference from a screw cover wireway, where the cover comes away entirely and gets set on the floor.

Three knockouts on the top and three on the bottom, which lets you feed conduit in and out on both faces without drilling the enclosure. If your run needs entries on the ends or sides, you'll be cutting those yourself or selecting a different configuration.

Through holes in the body, so it bolts up with your own fasteners to a wall, backboard, or strut rack. No mounting hardware, brackets, or strut clamps come with the trough, so add fasteners suited to your substrate when you order.

The 101012 HS carries CSA C22.2 certification, so it's acceptable for Canadian installations as well as US work. If your submittal package calls for the CSA mark on gutter and wireway, this one satisfies it.

That's the common use for a short hinged section like this. At 12 inches long with a 10 x 10 gutter and three knockouts top and bottom, it works as a junction or pull point where conduits break into the run. The hinged cover matters here, since a pull point gets opened for troubleshooting far more often than a straight run does.

Order Eaton B-Line part number 101012 HS. The HS suffix denotes the hinged screw cover version in the B-Line wireway line, so a number without it will land you a different cover style.

14 gauge steel, painted ANSI 61 gray. ANSI 61 is the standard light gray used across most industrial panelboards, control enclosures, and switchgear, so a run of these will match existing gear on a plant wall or an electrical room without looking like a patch.
