Post supports, often called post shoes or fence post shoes, are metal shoes designed for timber posts. Wood posts slide inside post shoes and are then securely fastened for added strength, support and stability. A post support is a great addition to any wooden post – whether it is for garden fences, gazebos, pergolas or decking. Post supports not only offer extra support and stability but also protect posts from water damage, fungal damage and insect damage.

International law has recorded a prohibition on the use of asphyxiating, poisonous or other gases in armed conflict since 1899, with the adoption of the Hague Declaration concerning asphyxiating gases. The treaty of Versailles, adopted at the end of the First World War, also contained a similar prohibition, as did the Geneva Protocol of 1925, which extended the prohibition to include bacteriological agents. The prohibition against the use of asphyxiating, poisonous or other gases in warfare is also reflected in the 1993 Chemical Weapons Convention (which prohibits all weapons which injure through the use of the asphyxiating, toxic, irritant, paralysing, growth-regulating, anti-lubricating or catalytic properties of a chemical, whether in its solid, liquid or gaseous state).

We stock 100mm x 100mm Hot Dip Galvanised Lightweight Easy Post and Ligthweight Easy Post in two sizes, 75mm x 75mm and 100mm x 100mm.
