All our holds have been designed since 2013 with double fastening system, being able to use cylindrical allen screws (FHC) or countersunk allen screws (CHC).
This allows us to reach the needs of all climbing gyms around the world. This system includes a stainless steel washer, so that neither the weather nor the cleaning liquid can damage it, thus giving the hold infinite life.
Furthermore, all our holds are from size M, take one second security hole, to use them with screws, so preventing any unwanted movement and offering a maximum setting of the holds to our ceiling.
