Carlon A540DS – Frequently Asked Questions

1) What does the Carlon A540DS ENT box back support actually do?
It's a PVC reinforcement piece that backs up an electrical box at a 1/2 inch knockout, giving the box a solid bearing point where ENT enters. Blue PVC, and it goes in behind the box rather than being the box itself, so you still need the box and your normal mounting.
2) How much space does the Carlon A540DS take up behind the box?
Small: 2 in depth/length, 1 in height, 1/2 in width. In a tight stud bay or a shallow ceiling cavity that footprint matters, and it's the number to check before you commit to a crowded rough-in.
3) What part number should I order for the Carlon ENT box back support?
Order Carlon A540DS. That's the manufacturer part number for the blue PVC ENT box back support sized for a 1/2 inch knockout.
4) Can I use this on a retrofit, or is it rough-in only?
Both. Carlon lists the A540DS for new-construction rough-in and for retrofit work where an existing box needs added backing at the 1/2 inch knockout. The limit on retrofit is access: you need to get behind the box to seat it.
5) Is a PVC box support OK in a damp or corrosive location?
The A540DS is molded PVC, so there's nothing in it to rust, which is why it holds up better than bare steel brackets in damp or chemically aggressive spaces. It's a mechanical support only, so the wiring method and box still have to be rated for the location.
6) Is the Carlon A540DS made in the USA?
Yes, country of origin is the United States. That matters on public and institutional jobs carrying domestic-sourcing language in the spec.
