The SkiErg requires very little assembly. There are a total of eight screws, and we include all necessary tools and clear instructions with lots of pictures. Hardware is included for attaching the SkiErg to a wall with 16” wooden stud spacing. For other types of wall construction, it will be necessary to purchase appropriate hardware. Alternatively, you can purchase the optional floor stand which allows for use on any level surface. Some assembly of the floor stand is required.
