CL-100 – Rebar Chair for Top Reinforcement (Pack of 30 Pieces)

The Crosslock CL-100 Rebar Chair is a platform-type self-locking cover block designed to provide accurate and reliable support for double reinforcement slabs. Unlike traditional steel chairs fabricated onsite, which often bend, rotate, or fail to maintain proper spacing, the Crosslock CL-100 ensures that the top steel remains at the correct height throughout concreting.

Why Choose Crosslock CL-100 Rebar Chair?

• Perfect for Double Reinforcement
  Specially designed for slabs where two layers of reinforcement are required. Placed directly on the shuttering, it supports the top layer of steel (distribution & main bars) with precision.

• Accurate Cover Height
  Keeps the distribution bar at 100mm and the main bar at 85mm above the shuttering. Ideal for slab thickness between 125mm to 135mm (approx. 5 inches).

• High Load-Bearing Capacity
  Made from engineered plastic with excellent strength, capable of handling heavy reinforcement without bending or collapsing.

• No Rotation or Sagging
  Unlike fabricated steel chairs, the Crosslock CL-100 does not rotate or cause sagging of steel. This ensures that even when the bottom layer of steel deflects under load, the top steel remains stable.

• Uniform Concreting
  The large holes in the design allow free flow of concrete, preventing voids and ensuring uniform bonding between reinforcement and concrete.

• Self-Locking Design
  At the crossing of the main bar and ring, the CL-100 locks itself in place, eliminating displacement during concreting.

Applications

• Double reinforced slabs

• Heavy load-bearing slabs
