Bison B Series ScrewJack pedestals are designed to support heavy pavers over any waterproofed structural surface. Each pedestal utilizes a patented threaded design, making the leveling process during installation a simple turn of the pedestal base. This allows contractors, designers and installers to accurately plan, precisely align, and uniformly install level decks with a combination of ease, speed and accuracy. Integrated spacer tabs ensure accurate spacing, lock the pavers in place, and allow water to drain.
The Bison Screwjack pedestal has a broad footprint that provides stability, is impervious to freeze thaw cycles, and offers a range of heights suited to almost any application. The Bison Screwjack pedestal (B-Series) reaches from 0 - 16' in height. Add bracing and couplers to reach up to 24' in height and the Weight Bearing Design Capacity is 1000 lbs/pedestal FS:2.
