No more fussing with nails. Comes with pre-inserted fasteners that can be installed without having to hold the nail! Ten-piece kit has enough hardware to hang up to five frames. Picture hanging wire is easy to use and install. Includes sawtooth and D-ring nailing hangers designed for frames without pre-attached hardware. Weight ratings are based on hangers nailed into studs and are not cumulative, so two hangers will not hold double the weight.
