Hanging art with the CG12/18-HK hook is easy as can be. The hook slides up and down the suspension cable and locks into place without any tools. The CG12/18-HK can be repositioned by pushing the release pin at the top of the hook. Excess cable will pass through the hook and can be coiled up and hidden behind the artwork. Multiple pieces of art can be hung by sliding extra hooks onto the suspension wire. When hanging pieces over 24" wide you may want to use two suspension cables. On wider pieces, two suspension cables can make leveling the art a little easier. When using two suspension cables attach the hook to the D-rings or screw eyes on the back of the frame.
