This 1.8m (6ft) x 75 x 75mm wooden fence post is a slim pressure-treated brown support for lower garden fencing, picket runs, trellis and other relatively light timber boundaries. Its 75mm square section provides a practical fixing face without giving the fence the heavier appearance of a 100mm post.
The 1.8m overall length is best considered for lower boundaries, picket fencing, trellis supports and other layouts where a longer 2.4m or 3.0m post would leave unnecessary material below ground. The key check is not the nominal fence height on its own: allow for the portion of post that must remain below ground and make sure the length still leaves the required finished height above it. If the required post length is not obvious from the planned fence height, use the fence post length calculator before ordering. It is better to select enough overall length at the start than to discover after digging that the post cannot provide both the desired visible height and the necessary below-ground section.
The timber is pressure treated to improve resistance to fungal decay, rot and insect attack. The brown treatment gives new timber a warmer appearance that coordinates naturally with similarly treated fence panels and fencing timber. As with any natural timber product, grain, knots, colour and surface character vary from post to post and the appearance will continue to weather outdoors.
Set the fence line out before digging so the post centres suit the actual panels or rail system rather than an assumed bay width. Keep each post plumb in both directions and check the top line as the run progresses. If the posts are being set in concrete or post mix, select a suitable material from the cement products range and follow its installation instructions rather than relying on one fixed amount for every hole.
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 an exposed boundary or where the fence carries a large solid surface, moving to a longer or larger-section post may be more appropriate. The shorter length is most useful when it genuinely matches the fence design rather than being cut down from a longer post. 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.
