BoMetals galvanized PRO-SLOT™ Anchor Slot is a stay in place form used in forming a channel into the face of cast in place concrete. Dovetail anchors are engaged into the slot to anchor brick, block or stone to the concrete. Pro-Slot is manufactured of G60 hot dipped steel in 22, 24 and 26 gauges in 10’ lengths. The product is standard with a polystyrene foam filler to keep the channel clear of concrete and to resist closure due to hydraulic pressure. Pro-Slot incorporates continuous nail grooves along the back edge of the profile.
