The 2.4m (8ft) x 75 x 75mm green/natural fence post combines the longer, versatile 2.4m format with a relatively slim timber section. It can suit lighter fence panels, trellis and site-built timber fencing where more post length is needed but a 100mm square post would be unnecessarily heavy.
A 2.4m post is a versatile length for many domestic fence runs because it gives useful scope for both above-ground height and secure fixing below ground. It is a better choice than the 1.8m version when a taller boundary or more generous below-ground allowance is required.
Mark the fence line and post centres before excavation, then check each post for plumb as it is installed. Ground conditions, fence height and exposure all affect how much of the overall length needs to remain below ground. The post mix calculator is useful when estimating setting material for a run, but the hole size and installation method still need to suit the site.
Pressure treatment helps protect the timber against fungal decay, rot and insect attack. The green/natural finish has the characteristic colour of freshly treated fencing timber and works well with similarly treated fence panels and rails. The shade is not a paint finish, so natural variation should be expected and the timber will change in appearance as it weathers.
The 75 x 75mm square section keeps the post relatively slim and gives a straightforward fixing face for lighter fence panels, picket fencing, rails and trellis. It is generally chosen where the visual bulk and extra material of a 100mm post are not required. A 75mm post is not simply a cheaper version of a 100mm post. Section size affects the amount of timber around fixings and the overall stiffness of the support, so the fence type and exposure should be considered before choosing the slimmer option. On uneven ground, the additional timber can be valuable when stepping the fence and keeping the top line consistent. Measure the proposed fence height at several points along the run before finalising quantities so that shorter sections are not accidentally specified where more post length is needed. The wooden fence posts range includes 75mm and 100mm sections in 1.8m, 2.4m and 3.0m lengths, so compare the complete combination rather than choosing on length or section alone.
