Split Ground Plates for supporting non-standard sized posts
Rotho Blaas Split Plates are designed for use on square posts. Similar in design to the Friulsider Split Ground Plates. Decking planed posts can differ in size we stock 95mm, 82mm and 70mm finished planed posts. For a firm fix standard post bases and anchors will often have to be packed out. Using these plates in pairs helps to solve this problem. They help to provide a quick and secure fit on planed post and sawn posts alike.
Robust design and construction
Manufactured using heavy duty 3mm Hot dipped galvanised metal the plates come with pre-drilled fixing holes. There are two for ground fixing and four for to fix to the post (screws are NOT included).
Finally we would recommend fitting each split plate to the posts before post installation. This reduces the possibility of the post moving compared to installing the plates on the ground or deck first and then fitting the post. You might also consider flush post anchors.
Rotho Blaas have a huger range of fixings products available. If there is a particular one you are after please email with the product information and product code and we can check the price and availability.

This elevated post support can support post sizes from 100mm x 100mm up to a maximum of 200mm x 200mm. This Simpson Strong-Tie adjustable post support allows for fine height adjustments after installation. Ideally suited for Awning posts, Pergolas and Verandas.
Where posts need to be fitted on an existing hard surface such as concrete or brick the Bolt-Down Post Supports are ideal. Due to their reduced base plate they can still be fitted if space is at a premium or access is restricted. Available in 75x75mm or 100x100mm.
