Arlington Industries FLBC4500 – Frequently Asked Questions

1) Will the Arlington FLBC4500 floor box work in an existing concrete slab, or only in a new pour?
New pours only. The Arlington 4.5 inch non-metallic floor box kit is built for placement before concrete is placed, which is why the pour cap is in the box, it keeps wet concrete out of the interior until the slab is finished. For a cut-in on an existing slab you want a retrofit-style floor box instead, not this one.
2) What is the difference between Arlington FLBC4500 and FLBC4502?
Hub count. The FLBC4500 is the 4-hub version of the 4.5 inch concrete floor box and the FLBC4502 is the 6-hub version. Same 4.5 inch round non-metallic body either way, so pick on how many conduit runs land in the box: four raceways into the box is the FLBC4500, six is the FLBC4502.
3) How much slab clearance do I need to lay out an Arlington 4.5 inch concrete floor box?
Plan the opening off 6.156 inches of width, not the 4.5 inch trade size. The 4.5 inch figure is the box designation; the actual body measures 6.156 inches across, so that is the footprint you keep clear of rebar and deck flutes when you set it.
4) What color is the Arlington 4.5 inch concrete floor box, and does it matter once it's poured?
Grey, and it only matters during the pour. The body and pour cap are buried in the slab, so the visible finish on the finished floor comes from the cover or service fitting you specify separately, not from the box.
