FSR Concrete Floor Box Pour Pans

Setting a floor box in a fresh pour is a levelling problem before it is an AV problem. The pour pan holds the box at the height the finished floor will be, takes the weight of wet concrete without shifting, and keeps the interior clean while the slab goes off.

FL-GRD200 is the 2 in deep pan sized for the FL-200. FL-GRD4 is the 4 in grade mounting kit for the deeper boxes. Both are placed and tied before the pour, not after.
