Fixing Anchor (PS) consists of two parts:
a plastic piece (with a plate), ribbed at the bottom and longitudinally slotted,
a metal zinc cold galvanized coil nail.
Drill a suitably deep hole f8 or 10 mm through an insulation board into the base material (concrete, brick etc.) to ensure the anchorage conditions. Push the plastic piece in and hammer a coil nail into it.
