Strongboys

The Strongboy Masonry Prop is a unique, easy to use, patented product. It is so simple you’ll wonder why you didn’t think of it yourself. Designed as a cost effective labour saving device the strongboy will fit any adjustable steel builders (‘ACROW’) prop with a 6” or 150mm square top plate.

The strongboy is used as an adaption to an Adjustable Steel Prop to provide support to brickwork and other construction support structures.

Due to the Strongboy's robust dynamics, it can be fitted between courses on a double-skin, brick cavity wall from either side. Therefore providing a cost effective, efficient and safe construction component.

Strongboy is zinc plated, this ensures a long life and low maintenance product.
