Uni-Pier is a (2) two Parts system
Comprised of a Uni-Pier Head (with integrated antcap* and fin plate) and a Uni-Pier Post (with integrated base plate).
Telescopic Adjustable Head
The Uni-Pier Telescopic Head provides the adjustment. The Uni-Pier Telescopic Head slides over the top of the Uni-Pier Post for Builders Grade and slips inside the Uni-Pier Post for Heavy Grade. The Uni-Pier Telescopic Head provides you with up to 200mm of adjustment. The Uni-Pier Head Sleeve is 300mm in length and is designed so that you have a minimum of 100mm of overlap in order to screw the Uni-Pier Head to the Uni-Pier post via 14-20 x 22 Self Drilling, Self Tapping, Galvanised, Class 4 Metal Tek screws. We recommend a minimum of six (6). Each Metal Tek screw is designed to carry a load of 800kgs.
Adjustable Screw Top Head (STH)
The Uni-Pier STH (Adjustable Screw Top Head) works in exactly the same way as the Uni-Pier Telescopic Head. The difference is that the sleeve is 200mm in length and the 200mm worth of adjustability is shared between 100mm of Telescopic Adjustment + 100mm of Screw Adjustment – simply by the turning of the nut. As the Sleeve is just 200mm in length, the minimum height actually attained by a Uni-Pier 200mm Post and STH Head combination is 255mm.
