Dowel material:	polypropylene
Material nail:	steel head with a plastic build-up.
Mounting type:	through impact with pre-drilled holes
Base:	concrete, building stone, solid and hollow bricks, hollow clay blocks, foam
The anchoring element:	lightweight insulation materials (rock wool, laminated boards, cork insulation, foam, polystyrene, fiberboard, etc.)
Advantages:	Impact installation method allows you to quickly install it. Use of a steel nail dowel preferred when fixing materials for giving fastener considerable bending load (mineral wool, cork insulation) and the plastic cap on the steel nail prevents "thermal bridges" that moisture does not form inside the walls.
