These Forgefix Pipe Support Posts are used in conjunction with single cliplock or open pipe clips. They snap in at the base of the clip and effectively raise the clip by 25mm. This additional clearance allows lagging to be fitted around the pipe. Further support posts can be stacked to accomodate thicker lagging.
It is essential the correct length of screw is used: ensure that the fixing screw used can pass through the pipe clip, the support post and then fully expand the length of the fixing plug.
