Measuring existing anchor bolts
If a replacement pole is required to suit an existing foundation, the base plate of the pole must be made to match the existing anchor bolts. The size and layout of anchor bolts can vary considerably; unfortunately, there is no "standard" size.
When ordering a replacement pole, please indicate:
- diameter of existing anchor bolts
- either the BCD or BSD of the 4 existing anchor bolts (see illustration below)

We will then be able to build the base plate of the new pole to suit your existing anchor bolts.
