Allgäu Holds - Conglomerate Jugs L #2 (Climbing Holds Set of 15 Climbing Holds from Allgäu Holds, made in Germany. Quantity: 15 holds, size M. The holds are made from polyurethane resin (PU), which is additionally processed with a special mineral filler. Unlike pure PU holds, this combination significantly increases abrasion resistance. The stability and break resistance of the holds are also very good despite the mineral filler. The climbing holds come in the colors white, blue, purple, dark green, and neon, and are not UV-resistant. This means that outdoor use may cause discoloration of the climbing holds. However, this does not affect the stability of the climbing holds. Screws and nuts are not included and must be ordered separately.
