Steel City BL111-1 – Frequently Asked Questions

1) What trade sizes do Steel City snap-in knockout blanks come in?
Six trade sizes cover the standard knockout range: 1/2 inch (BL111-1), 3/4 inch (BL112-1), 1 inch (BL113-1), 1-1/4 inch (BL-114-1), 1-1/2 inch (BL-115-1) and 2 inch (BL-116-1). Match the blank to the trade size of the open knockout, not to the conduit you removed.
2) Will a snap-in blank close an unused knockout on a rigid or IMC installation?
That is exactly what it is for. The Steel City blank is rated for rigid and IMC work and snaps into an open knockout to close it off, so an enclosure or box left with an unused opening after a conduit change can be sealed without a screw-on cover plate.
3) I have a mix of 1/2 inch and 3/4 inch open knockouts on a panel. Do I order one part for both?
No, the blanks are size-specific. Use BL111-1 for each 1/2 inch opening and BL112-1 for each 3/4 inch opening. A blank sized for a larger knockout will not retain in a smaller one, and an undersized blank will fall through.
4) Are these knockout blanks steel or plastic?
Steel. That matters on commercial and industrial boxes where an inspector expects the closure to match the metallic enclosure, and it keeps the box surface consistent for painting or grounding continuity of the enclosure itself.
5) Do I need any tools or extra hardware to install a Steel City blank?
No separate hardware. These are snap-in style, so the blank seats into the knockout under hand pressure with no nut, gasket or screw supplied or required. Each part number is sold as a single piece, so count the open knockouts before ordering.
