Only three models of Archatrak ’Prime’ adjustable height pedestals are needed to span the height range 1 1/4″ to 16 1/2″. The unique design feature of our ‘Prime’ deck supports with concentric screwed columns not only minimizes installation time, but more importantly, resolves the frustrating and costly issue common with most screw adjustable pedestal systems in accurately estimating pedestal height requirements pre-installation and subsequently dealing with unexpected height variations on site. “Prime” model PR1 extends from 1 1/4″ to 2 1/2″, typically requiring two pedestal sizes. “Prime” model PR2 covers the range 2 1/2″ – 6″, typically needing 2 or 3 pedestal sizes.“Prime” model PR3 covers the range 6″ – 16 1/2″ typically needing a minimum of 3 pedestals sizes. Extension elements can be added to the PR3 pedestal to extend the workable height to 37″. Add one extension to reach 24″, two extensions to reach 30″ or three extensions to reach 37″. A self-leveling head provides automatic slope adjustment up to 5°. An optional headlock is available for easily switching to a fixed head as required. “Prime” deck supports have rubber faced heads for superior noise suppression and shock absorption and incorporate inbuilt spacer tabs which can be easily snapped off where not required.
