Thomas & Betts HB1BL – Frequently Asked Questions

1) What does the Thomas & Betts HB1BL handy box cover do?
The HB1BL is a blank cover for a handy (utility) box with a 1/2 inch knockout in the face. Blank means no device opening, so it closes off a box used as a junction or splice point, while the 1/2 inch knockout lets you bring a fitting or trade size 1/2 raceway through the cover when you need it.
2) Can I mount a switch or receptacle in the HB1BL cover?
No. It is a blank cover, so there is no device opening. For a switch or receptacle on a handy box you need a device cover (toggle switch cover or duplex receptacle cover) instead. Use the HB1BL where the box is a junction, splice, or pull point, or where you are bringing 1/2 inch conduit or a cable connector through the knockout.
3) Is the HB1BL handy box cover metal or plastic?
Non-metallic, in grey. That matters if you are matching it to a non-metallic handy box, or if you want to avoid a metal cover that would need bonding. Crews used to steel utility covers should expect a different look and feel here.
4) Do I get more than one cover when I order the HB1BL?
The HB1BL is sold each, one cover per unit, so order a piece per box you are closing up. Property maintenance and MRO buyers restocking a truck should count openings and order accordingly rather than assuming a carton.
5) How many knockouts does the HB1BL cover have besides the 1/2 inch one?
Just the single 1/2 inch opening called out in the part description; the cover's knockout count is listed as zero beyond that. So plan on one penetration through the cover, and take any additional conduit or cable entries through the knockouts in the handy box itself.
