Buckingham Crib Jacks

Crib jacks are the dependable backbone of house lifting and structural support. Built in the USA and field-proven, Buckingham crib jacks pair with cribbing to safely lift, level, and temporarily support structures during repairs and moves. Use them for house leveling, floor-joist repair, beam installs, underpinning, and other temporary support work. Choose single-acting for simplicity or double-acting for powered retracts and faster resets.

What it’s for

House leveling, beam installs, floor-joist repair
