Adbri-Grey Block Knock-out Bond Beam 20.20

The Adbri Grey Block Knock-out Bond Beam 20.20 is a grey block designed for structural masonry projects. The function of a Knock-out Bond Beam is to provide a continuous channel for horizontal reinforcing steel and concrete, increasing the structural integrity and strength of masonry projects. These blocks can be used for:

• Bond beams in reinforced masonry walls
• Retaining walls
• Lintels over doors and windows
• Reinforced concrete block walls

Compared to a standard concrete block, a Knock-out Bond Beam block has removable sections that create a continuous channel for horizontal reinforcing steel and concrete. This provides additional reinforcement for structural walls.

Yes. When the knock-out sections are removed and reinforcing steel is installed, the channel is filled with concrete to create a reinforced bond beam.

The dimensions of the Adbri 20.20 Knock-out Bond Beam are: 390mm (L) × 190mm (W) × 190mm (H)

This block is part of Adbri's 200 Series masonry range and is compatible with standard 200 Series concrete masonry blocks.
