Strongboys or Prop attachments are used to install Steel Beams, RSJ's, Lintels and Windows.

The strong boy attaches to the top of the acrow prop and is then inserted into the opening you’ve created in the brickwork to safely support the structure.

XL strongboys are needed when the cavity wall is larger so these have a 4” longer and stronger plate.

At QBE we stock strongboys both with and without handles.
