Unifix / FM Pipe Spacer Support Posts

These pipe spacer support posts are designed to hold pipe clips clear of the wall or surface, giving enough room for lagging or insulation to sit properly around the pipe. They comply with British Water Supply Bylaw No.49 on insulation clearance, so when you are working on domestic or commercial water systems and need to demonstrate compliance, these do the job. If you are using pipe clips on insulated pipework, this is the kind of detail that gets picked up on inspection. Worth having on the van.

Each post provides clearance for lagging up to 30mm thick, which covers the majority of standard pipe insulation used on hot and cold water systems. Where you need more clearance, the posts can be stacked, so you are not stuck if the insulation is on the chunkier side.

Using Pipe Clips with Spacer Support Posts

These spacers are designed for use with single Openlok and Kliplok pipe clips, both of which are common on UK plumbing and heating installations. The post fits between the clip and the fixing surface, lifting the pipe away to allow full lagging coverage without compressing or bridging the insulation.

One thing worth knowing before you order: the sizing does not follow the logic you might expect. The 15mm spacers are used with 28mm pipe clips, not 15mm clips. It is one of those product quirks that catches people out the first time. Check the size guide before you order and save yourself the hassle of a return.

Supplied in boxes of 100, these are priced well for the volume and suit anyone working on larger installs or carrying stock for regular plumbing work.
