The installation spacers are plastic components commonly placed between hollow-core slabs and load-bearing wall structures. The installation spacers ensure there is sufficient clearance beneath the hollow-core slabs, which in turn ensures that the cast-in-situ concrete flows reliably beneath them. The installation spacers can be connected to one another using their recesses and projections. This allows the installation spacer to be built up to the required height. The pack contains 50 × 10 mm, 50 × 5 mm and 100 × 3 mm installation spacers.
