CNL Contraction Joint Straight-Up 125-200mm x 3.0m

The Connolly Straight Up Contraction Joint is a continuous pour solution for contraction joints in slab on ground applications. The straight profile guarantees that the load is transferred through the dowels only.

Connolly Straight Up Contraction Joints are a roll-formed galvanised steel section to provide a leave-in-place formwork. The profile is fixed in place using the patented peg and wedge system.

The Straight Up Contraction Joint has pre-formed holes which allow it to be used in conjunction with Connolly Universal Dowel Sleeves (UDS). The Universal Dowel Sleeves are installed in the steel section using the patented Connolly twist-fix feature. The preformed holes will accommodate round dowels up to 30 mm diameter and square dowels up to 24 mm.

The Straight Up Contraction Joint profile is available in 3 m lengths for slab thicknesses from 125 mm to 200 mm. Custom heights, lengths (up to 3m), and dowel configurations are available on request.

The Straight Up Contraction Joint utilises the Key Joint range of permanent and removable capping and rebate moulds.
