Our Circular Cartwheel Spacers are the industry standard for ensuring accurate concrete cover in vertical structures. Whether you are pouring reinforced concrete columns, retaining walls, or piles, these spacers provide a 360-degree "buffer" between the rebar cage and the formwork.

Manufactured from high-strength, durable plastic, the "wheel" design allows the spacer to roll smoothly against the shuttering during installation, preventing snagging or displacement. The unique locking clip in the center is designed to grip the rebar tightly, ensuring the spacer stays exactly where you place it, even during heavy vibration or high-pressure concrete pours. The open-spoke design is engineered for maximum concrete flow, ensuring the wet mix reaches all areas without leaving unsightly "ghosting" or voids on the finished surface.

Product Type: Circular / Cartwheel Rebar Spacer.

Available Cover Sizes: 25mm, 40mm, 50mm.

Rebar Compatibility: Fits bar diameters from 6mm up to 20mm.

Material: Heavy-duty, non-corrosive Polypropylene.

Application: Vertical formwork, columns, walls, and pre-cast concrete.

Profile: Minimal surface contact design to reduce visibility on finished concrete.

1. How do I know which bar size to choose?

It is important to match the clip size to your steel. If you are using standard 10mm rebar, the 4-12mm clip is perfect. If you are using heavy 16mm or 20mm structural steel, you must select the 12-20mm clip to ensure the spacer doesn't snap or slide during the pour.

2. What is the benefit of the 50mm cover option?

The 50mm cover is typically used for heavy-duty foundations and external structures where a thicker layer of concrete is required to protect the steel from corrosion and environmental factors.

3. Can I use the 12-20mm wheel on a smaller 8mm bar?

We don't recommend it. The clip will be too loose, and the spacer may slide down the bar when the concrete is poured. For an 8mm bar, always use our 4-12mm or 8-12mm specific clips for a secure grip.

4. Do they slip down the rebar?

No. Each spacer features a heavy-duty integral clip that "bites" onto the rebar. They are designed to stay in position even when concrete is being poured from height or during the use of immersion vibrators.

5. How many spacers do I need to use?

For vertical columns and walls, we generally recommend placing spacers at 500mm to 1000mm intervals along the rebar. You should place them on all sides of the cage to ensure the steel remains perfectly centered.
