Props and Column Clamps
Heavy-duty props and column clamps provide temporary support for slab formwork, shuttering and column alignment.

Heavy-duty adjustable steel props (acrow / shoring posts) engineered for slab support, temporary load distribution and shoring during construction.
The Malmo adjustable prop is the workhorse of any concrete pour. Quick to set, infinitely adjustable within range, and built tough enough for site after site.

Heavy-duty props and column clamps provide temporary support for slab formwork, shuttering and column alignment.

The telescopic prop adjusts to the required height using pin and collar movement, giving reliable support during casting and reshoring.

Adjustable props distribute vertical load through the shuttering arrangement and help keep slab support stable while concrete cures.

Column clamps align and restrain shutters around vertical formwork, reducing movement during pouring.

Accessory details support practical site fitment where props, clamps and shuttering members meet.

Base jacks adjust scaffold or formwork height from the bottom and help compensate for uneven ground levels.

The jack is inserted at the bottom of the vertical or pipe and adjusted using the nut on the threaded rod.

Base plates spread vertical point loads over the floor or ground surface to improve bearing and stability.
