Verified support dimensions
For the PSB75600G model, the pointed spike section is 600mm and the post holder is 150mm, giving a 750mm overall length. These measurements describe different parts of the support; the holder is for nominal 75 × 75mm timber.
Choosing a ground spike for fence posts
Select the support for the actual timber dimensions and the fence requirements. Ground needs to allow the spike to be driven straight and securely; an obstruction, loose ground or unsuitable base may require a different installation method. Check the supplied dimensions before choosing by a nominal size or length alone.
Place the matching driving tool in the holder to help protect it during installation, check the alignment as work progresses, then fit and clamp the timber. Do not strike the unprotected holder directly or treat the driving tool as a replacement for a hammer.
Is this a repair spike or a bolt-down shoe?
This is a drive-in ground support for timber posts. A 75mm repair spike is a different support intended for replacing a post within suitable existing concrete. A 75mm bolt-down shoe fixes through a base plate to a suitable hard base.
