Square Plenum Box, Drawn, 2-1/8 in. Deep, Eleven 1/2 and Five 3/4 in. KO's. This product is manufactured in Mexico. It is manufactured by RACO. Review: Good product - Being that they're plenum boxes, I'm not going to complain about the lack of mounting holes. However they really should have included 8-32s as even the cheapest 4s boxes usually do. They worked great with raised covers and since they have rounded edges they look better than the perfectly square ones sold locally. Review: Industrial strength - This is a well built junction box, however it does not come with screws, no threaded ground screw, and no attachment holes. Not a choice for someone that's installing 25. I only had for to instal four, so not a problem. I had screws that fit and I drilled four mounting holes along with a ground mount which I drilled and tapped to a #10 green ground screw. I was going to give this four stars but because this box is so robust I had to give this five stars. This is actually industrial grade, thick and heavy. ## Features - Drawn construction - UL Listed - 30.3 cu. in. capacity ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B003A2GWX4 | | Best Sellers Rank | #22,638 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #46 in Electrical Boxes | | Brand Name | RACO | | Capacity | 30.3 Cubic Inches | | Color | Gray | | Customer Reviews | 4.6 4.6 out of 5 stars (259) | | Finish Type | Painted | | Global Trade Identification Number | 00050169002391 | | Included Components | motor-accessories | | Installation Type | Fixed" or "Permanent | | Item Dimensions D x W x H | 2.18"D x 4"W x 4"H | | Item Type Name | Eleven 1/2 and Five 3/4 in.
