Provides a hole in the concrete on the edge of a slab. This can be used to insert scaffold tubing for temporary balustrading of a concrete structure.
The unit is attached to formwork and cast into the concrete (about 2-4m apart).
After casting, the cap is removed from the plastic tube and the exposed hole can now be used to insert a 50mm scaffold tube.
* Eliminates expensive drilling of holes.
* Provides a safe method of erecting a temporary fence during the construction of concrete buildings.
