PVC Box Rough In - In concrete

[shaw0486]

Hi guys,
I have come across something that has me stumped. We are roughing in a small stadium and we have a lot of concrete wall rough in. We were planning on using masonry boxes for our step lights however the interior dimensions will not work with the light. I have been searching for a PVC device box that is listed for concrete embedment and cannot find one. Am I missing something. What have you guys done? I need a box with the interior dimensions of 3" x 2" for the step light to fit.

Have you asked the manufacturer of the light? They've probably come across it before.
Second I'd call the engineer who spec'd it if the manuf. can't help you out.

Have you looked into ENT type mudboxes?

Carlon makes one with a device ring.
