This device fits to the cold end / un-driven end of the Bunyan striker tube. The kerb crawler simply slides along the top of the kerb and it permits the screeding of the concrete right to the face of the kerb. This allows you to place your precast or poured concrete kerbs and then pour the slab.
The kerb crawler is available in two sizes dependent on the height of your kerb. Both feature easy adjustment for fine tuning height.
