This large ratchet adaptor comes in one piece and is easy to split apart for installation. The ratchet allows height variance for installation. The black plastic price channel accepts 1 1/4"H price tickets, FlexChannel® ticket moldings and other signage accessories. A key feature in the adaptor is the grip beading that prevents the piece from sliding side to side. This large ratchet adaptor is compatible with Hussmann® Flat PTM, Metro® Style Wire Shelving and Bare Kysor/Warren® Shelving.
