    Image of Product. Front orientation. Jacks. Scaffold Leveling Jacks.
    Swap these jacks with the base plates on your scaffold to create a level foundation on uneven ground. They adjust in increments less than an inch, so you can set each leg of your scaffold to the exact height you need. Made from galvanized steel, these jacks resist rust and hold up to outdoor use. For safety and stability, the top 6" of the threaded stud slides into the scaffold frame and isn’t usable.
    Note: Leveling jacks meet OSHA and Cal/OSHA dimensional and construction standards. Check local, state, and federal codes, including OSHA, for safe set up and operating practices.
    Hollow—Hollow jacks are lighter in weight than solid jacks, so they’re easier to handle.

    Levelers with Foot Lock, Stabilizing

    Arm, and Swivel Shoe

    Keep your ladder level even when the surface isn’t. These levelers adjust one side of your ladder by up to 10". A foot lock allows for hands-free operation. They work with most Type 1, 1A, and 1AA fiberglass and aluminum extension, straight, and step ladders.
    Note: Check local, state, and federal codes, including OSHA, for safe set up and operating practices.
    Stabilizing Arm—Levelers with a stabilizing arm help prevent side tipping, especially when you’re working on slopes. The arm folds out to widen the stance of your ladder by about 16".
