The 2.4m (8ft) x 100 x 100mm wooden fence post is a substantial all-round timber support for garden fencing. The combination of a 100mm square section and 2.4m overall length makes it well suited to projects where both a broad fixing face and useful below-ground allowance are important.
The 100 x 100mm square section gives a broader fixing face and a more substantial support than a 75mm post. It suits fence runs where a heavier timber post is preferred, including substantial panel fencing and site-built timber boundaries.
The 2.4m length gives considerably more flexibility than a 1.8m post and is a practical starting point for many full-height garden fencing arrangements. It leaves more timber available to divide between the visible fence and the below-ground section, which is useful where ground conditions or exposure call for greater embedment. 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 larger section is useful when the post needs to provide more fixing area for rails or panels, but it also creates a visibly heavier post line. If the fence is relatively light, compare the 75mm alternatives rather than specifying the larger section by default.
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. 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.
