The MF378JB Multifunction Level Jack is a rugged, adjustable base support designed specifically for 6 ft Multifunction (Baker-style) scaffold units. Whether you're working on sloped surfaces, uneven ground, or need fine-tuned height control, this level jack delivers the stability and flexibility required for safe and efficient elevated work.

Key Features:

• Threaded Height Adjustment
  Each jack features a precision acme-threaded rod that allows for up to 18 inches of vertical adjustment, enabling users to level scaffolding configurations with pinpoint accuracy—even on uneven or sloped surfaces

• Independently Adjustable Legs
  Designed to be installed at the base of each scaffold frame, these jacks allow individual leg height control, ensuring a perfectly level platform regardless of terrain

• Welded Base Plates for Stability
  The 5" x 5" steel base plates are welded to the bottom of each jack, providing a solid, non-slip foundation that resists shifting and sinking on soft or irregular surfaces

• Heavy-Duty Load Capacity
  Rated to support up to 1,000 lbs per jack, the MF378JB is built for demanding jobsite conditions and multi-user setups

• Ultralight Construction
  These jacks are part of ScaffoldMart’s Ultralight series, featuring hollow rods that reduce weight without compromising strength—making transport and setup easier

• Easy Installation
  Simply insert the jack into the bottom of the scaffold end frame and adjust using the wingnut. No tools required for setup or adjustment.
