Two-Pack Adjustable Support Jack
This two-pack supplies a pair of adjustable support jacks built from galvanised steel for temporary shoring of floors, deck foundations, RV steps or furniture. Each jack spans a 4-inch to 7-inch height range and carries a 4400.00-pound capacity, giving DIYers and contractors a compact yet strong prop for confined spaces.
Sustained Load Behaviour
Under continuous load the galvanised steel body resists deformation and the integrated safety lock set screw prevents the threaded collar from backing off over time. The 1.3-pound weight per unit keeps the assembly light enough for repositioning while the 4400.00-pound rating remains stable throughout extended use.
Build Quality and Daily Use
The housing and screw mechanism are coated for rust resistance, suiting damp basements or outdoor deck work. Height changes are made by turning the screw with a pipe wrench and then locking the positioning nut, a straightforward process that requires no specialised tools and fits tight clearances where larger jacks cannot reach.

Questions about this item
Does the jack produce any vibration or heat during continuous load-bearing use?
The galvanized steel jack is a static support device with no moving parts under load, so it generates no vibration, noise or heat during all-day use.
What tools are required to adjust the 4"-7" height and secure the safety lock set screw?
A pipe wrench is needed to turn the adjustment screw to the desired height, then the positioning nut is tightened by hand to lock the safety set screw.
Can the 4-inch square base plates sit directly on an existing concrete slab without additional footings?
Yes, the 4" x 4" base plates are designed to bear on solid, level surfaces such as concrete slabs or timber beams for temporary shoring.
