Start building your scaffold with end frames. They have pins with locking arms welded to each side for attaching braces. End frames on the same level must be the same height.

Use braces to secure end frames together. The ends of each brace fit over the pins on an end frame, and a locking arm secures them in place.

For every pair of end frames, you’ll need two cross braces—one for each side of the scaffold.

Use braces to secure end frames together. The ends of each brace fit over the pins on an end frame, and a locking arm secures them in place.

If your platform is over 10 ft. high, add a bottom diagonal brace on the lowest level. Also known as gooser braces, they connect two opposite corners to add stability and keep your scaffold square.

For a mobile scaffold, use casters as the base. You’ll need at least four—one for each corner of the scaffold.

If your scaffold is 20 ft. or taller, use outriggers to extend the base and increase stability. You’ll need a base plate or caster on the end of each outrigger—attach them with a toggle or pig tail pin (all sold separately). You can also use leveling jack feet. You’ll also need a cross brace (sold separately) to join each pair of outriggers and keep them square. The outriggers have welded pins for mounting cross braces.
