Concrete Bar Chairs
PROMAXA Concrete Spacers are ideal for slab on-ground and wall applications, for steel reinforcing in major civil and infrastructure projects. They have high load capacity and are heat tolerant in the event of a fire. The wider flat- based spacer has rust-resistant tie wire ensuring a stable concrete bar chair, reducing rolling, and tilting when being installed. The uniquely tapered design provides interlock within the structure, preventing fallout.
Features:
- Galvanised-looped tie wire
- Size imprinted on side of spacer for easy Identification
- Tapered design for ultimate interlock
