125 x 100mm Mortised posts with post top variations

Our mortised 125 x 100mm is a larger section post, therefore more robust than the standard 100 x 100mm mortised posts. We can offer a range of decorative post top weathers.

What length of mortised post do I need?

The post length required for closeboard and palisade fencing depends on several factors. The main ones are:
1/ Overall height of the fence.
2/ Post top required.
3/Ground- firm or soft.
4/ Fenceline – flat or on a slope.
5/ Type of fence – closeboard, palisade etc.
If you are unsure what post length you need, please ask our sales team for help and a complete quote for your materials.

Please note: All mortised treated softwood posts used for closeboard or palisade fencing are susceptible to natural movement or shaking (vertical cracks in the wood) as the timber expands and contracts during the normal weathering process. However, these problems do not usually affect the structural integrity of the post and will mostly disappear when colder, moist weather returns. Therefore, this is not considered to be a defect unless very severe.
