The M model is part of the range developed for professionals. Its square shape and the stainless steel insert in the moulded fastener provide exceptional resistance. With 5 mm spacing between the boards, the hardWood Clip™ M fastener is designed to let wood boards both expand and contract.
When wood with the appropriate moisture content is used, the M fastener ensures that there are no abnormally large gaps between boards and that they don’t abut against each other either.
