Review: Extra room for wire fill in a electrical box - Just the size needed when a 1900 wont do..def would buy again. Review: Great multipurpose box has it all! - This box is wider and deeper than a standard 4x4 box, so it has more room inside. Not only is it the higher-quality welded steel type of box, but there are lots of knockouts and mounting holes to support almost any use. The listing photo shows an older version of the box with some differences from the current model, so I uploaded photos of the current 2023 version. Key features: 1) 15 total combo 1/2 & 3/4 knockouts, 3 on each face, plus one more 1/2 inch only on the back. The combo knockouts are designed so that if you knock out only the inner 1/2 inch disc, a standard 1/2 locknut makes a good bond with the rest of the box so no bonding jumper is necessary on attached conduit. 2) A raised ground bump for a standard green grounding screw - the bump leaves room for the screw end even when the box back is surface-mounted to a support. 3) Plenty of additional holes on back and sides for mounting the box or securing lugs or other fittings. ## Features - Combination screw heads provide for faster installation. - TKO knockouts allow for design and installation flexibility. - 4-11/16 in.

I saw an an answer below, but what does that mean? is there a specific hole pattern?** A: You need something like "4-11/16 in. Steel Metallic 2-Gang 2-Device 1/2 in. Raised Square Cover" Raco 841 which is a cover with a raised-edge opening that holds 2 outlet/switches/devices. The raised edge is so you can run drywall right up to the opening edge. A blank cover would be "4-11/16 in. Steel Metallic 2-Gang Flat Blank Square Cover" Raco 832SP ## Customer Reviews ### ⭐⭐⭐⭐⭐ Extra room for wire fill in a electrical box *by 1***L on June 14, 2026* Just the size needed when a 1900 wont do..def would buy again. ### ⭐⭐⭐⭐⭐ Great multipurpose box has it all! *by M***N on March 31, 2023* This box is wider and deeper than a standard 4x4 box, so it has more room inside.
