Acciaio Inox 302
In this model, the double-ring spring is made with a very narrow inner diameter so that it can be fixed to the pile with simple wood screws.
The screws are useful in the presence of piles with very hard wood or when it is necessary to avoid blows to the pile for the insertion of the fastening staples.
Made in stainless steel, Inox 302. Diameter 2,5 – 3,0mm
