Most readily available shelving systems are not adequate for shop use. This one is.
The optional hang track supports 1000 lb (200 lb per installed screw) and lets you space the uprights variably (not necessarily on stud centers).
The standards are all double slotted, and can be joined together using an optional connector (item H).
The double brackets are load rated at 150 lb per bracket, while the supported brackets will hold up to 300 lb per bracket. The fast-mount bracket lets you hang the standards from the wall top plate or from a joist to support 600 lb.
An excellent and affordable heavy-duty system. Galvanized steel finish.
Please note that the components in this shelving system and the components in the white powder-coat shelving system are not interchangeable.
