Extension Planks

Adjust the length of these planks to create a work platform on ladder jacks, trestle ladders, and other supports. The surface is ribbed to prevent slipping.
250 lb. capacity planks are for one person. A spring-set lock secures them at the length you choose.
500 lb. capacity planks hold two people at a time. They hook onto your supports with rung locks, which keep the plank from slipping off or changing length while you work.
Note: Planks that have OSHA or Cal/OSHA specifications listed meet dimensional and construction standards. Check local, state, and federal codes, including OSHA, for safe setup and operating practices.

Ladder Plank Supports

Also known as ladder jacks, these supports hold a plank between two straight or extension ladders to create a scaffold. Supports fit round or D-rungs, attaching to three rungs on each ladder. Use the adjustment notches to set the angle of the plank. Capacity is 500 lbs. per pair.
Note: Ladders and planks must have a minimum 250-lb. capacity.

Uneven Surface Plank Stands


With a tripod base and adjustable legs, these stands help you create a stable, level work platform on stairs, slopes, and uneven ground. Pair with scaffold planks or stages. A pair holds up to 600 lbs. The legs adjust in 1 1/2" increments, so you can set each one to the exact height you need. Rubber feet keep them from slipping on smooth surfaces. Made of aluminum, these stands are lightweight and corrosion resistant. When your work is done, fold them flat and store them, or use the handle to carry them to another job.
Note: Work platforms that have OSHA specifications listed meet dimensional and construction standards. Check local, state, and federal codes, including OSHA, for safe set up and operating practices.
