Base Connections
- a general guide

Square and circular base plates are standard. Square base plates are typically for octagonal poles below 16m in height. Circular base plates are for all circular, hexadecagonal and octagonal poles above 16m in height. Alternative hinge or shear base connections are also available. See below for drawings and size tables of base options.

Note
All base connections which are not standard will be designed specifically for each situation. We will happily discuss any special requirements and provide information on request.

Note
(1) base plate and foundation sizes can be specifically designed for each
project. The tables are intended as a general guide and will vary substantially due to location and windage area. (2) PCD = pitch circle diameter. H/D = holding down bolts.
O/D = outside diameter. A/F = across flats of octagonal or multi-sided poles.
