Unifix / FM Products Pipe Spacer Support Posts

Pipe spacer support posts solve a problem every plumber knows too well: how to get proper insulation clearance around pipework without bodging it with offcuts of timber or cable ties that look terrible and fail inspection. These spacers fit between the pipe and the mounting surface, creating the gap you need for lagging up to 30mm thick. They work with Openlok and Kliplok pipe clips, giving you a clean, compliant installation that actually looks like a professional fitted it.

The spacers comply with British Water Supply Bylaw No 49 on insulation, which means you can use them on jobs where compliance matters and someone might actually check. Available in 15mm and 22mm sizes to match standard copper and plastic pipe diameters, they come in boxes of 100 so you have enough for a proper job without running back to the merchant halfway through.

Why Spacers Beat the Alternatives

The traditional approach to creating pipe clearance involves timber battens, plastic offcuts, or simply hoping the insulation will somehow squeeze into a gap that was never big enough. None of these methods look professional, and most of them fail to meet regulations when someone decides to actually read the bylaws. Pipe spacer posts give you a consistent, repeatable clearance every time. They stack for increased distance from the mounting surface when you need thicker lagging or want to run multiple services behind the pipework.

Stacking is genuinely useful on commercial jobs where insulation requirements are stricter or where you are running hot and cold services close together and need extra separation. Each spacer adds to the overall standoff, so you can build up whatever clearance the job demands without switching to a completely different fixing system.

Installation With Clip Systems

These spacers are designed to work with single Openlok and Kliplok pipe clips, which are the standard clip types you will find on most plumbing and heating jobs in the UK. The spacer sits between the clip and the wall or joist, and the clip holds the pipe as normal. This means you are not adding complexity to the installation. You are just adding the clearance that should have been there from the start.

The 100-box quantity makes sense for contract work where you are fitting out bathrooms, kitchens, or plant rooms and need consistent spacing throughout. One box will cover a reasonable domestic installation with spares left over, or contribute to a larger commercial fit-out where multiple trades need the pipework finished before they can continue.

For anyone who has ever tried to retrofit insulation around pipework that was fitted too close to the wall, these spacers are the fix you wish had been used originally. Getting it right first time saves hours of messing about later.
