This foaming wheel & tire chemical applicator is machined out of a solid block of dark gray schedule 80 PVC, 1 foot X 1 foot X 2-1/2 inches thick!! It's unique triangular shape allows your staff to snag it with a prep hose or a wash down hose, no problem; the hose just slips over the top of the frame without any damage to the applicator!
