Konsa rebar chair spacers support horizontal reinforcement in suspended slabs, beams and floor slabs while maintaining the specified concrete cover. The concave seat accommodates rebar from 6 mm to 40 mm, with cover options from 15 mm to 150 mm. Sizes from 60 mm to 100 mm are manufactured with a wider base for improved stability on softer supporting surfaces. Typical usage is approximately 2–4 spacers per square metre, subject to the reinforcement layout and project requirements.

Code: CR30
Konsa concrete chair spacers provide stable support for reinforcement while maintaining the required concrete cover. Manufactured from 32 MPa concrete and supplied with blackened wire ties, the spacers are water-cured for 15 days and dry-cured for a further six days to develop their intended strength. Available cover sizes and spacer diameters are listed in the product specification table.
Code: H25
Konsa heavy-duty plastic chair spacers support horizontal reinforcement in slabs and precast concrete applications. Their small contact area helps minimise the visible footprint against the formwork, while the concave seat accommodates rebar from 6 mm to 50 mm. Cover heights range from 25 mm to 80 mm. Spacers can be supplied with galvanised binding-wire ties by adding “W” to the product code, and custom sizes are available subject to manufacturing requirements.
Code: WS36
Konsa plastic wheel spacers clip onto reinforcing bar to maintain consistent concrete cover around vertical reinforcement. The circular design provides support through 360 degrees, making these spacers suitable for columns, walls and beams. Multiple models are available for different rebar diameters and cover requirements; select the correct product code from the specification table for the reinforcement used on the project.
Code: C20
Konsa heavy-duty plastic combination chair spacers provide several cover heights from a single spacer, simplifying stock selection across slabs, walls, columns and precast concrete work. The compact formwork contact area and support for rebar from 6 mm to 40 mm make them a practical alternative to fibre-cement spacers. They can be supplied with or without galvanised binding-wire ties for faster placement and secure positioning.
