Projack is a unique, low-cost stackable deck jack.
Projack’s 5mm, 15mm, 30mm and 60mm spacers are stacked in any combination and sandwiched between a Projack base and top, allowing you to construct jack sizes from 5mm through to 300mm.
The unique design allows individual jacks to be constructed at a fraction of the cost of traditional screw-type deck jacks.
