OOK 50036 Male Quick Coupler (22-18 Ga.), Red;

OOK Steel Concrete Picture Hangers are specially designed to help you hang art work on concrete and brick walls. Each hanger has a channel guide and installs easily with brass-plated, bendless masonry nails. Hangers hold up to 50lbs and Bendless nails are ideal for concrete/brick or hardwall surfaces where normal nails will not work. Pound ratings are not cumulative (meaning that two hangers will not hold double the weight, two hangers will still only hold up to 50lbs).
