Tools Needed for Installation

Shed Safety and Care

• Unit must be stored completely packaged in a cool, dry place until ready to assemble.

• Many wood pieces (e.g. wall studs) are able to be installed with either end up or down, or turned 180
degrees. In these cases, look at the pieces before attaching them and decide which position is best.
For example, you may hide a blemish on a stud by fastening siding to that side of the stud.

• Look at all the trim pieces before installing, and choose the best ones for the front of the shed.

• Keep roof clean of snow and leaves.

Assembly Day Tips

Assembly Day Tips

• Complete site preparation before unpacking parts and beginning assembly.

• DO NOT attempt to assemble on a day with strong winds.

• DO NOT attempt to assemble on days when temperature is below 32 degrees.
