Children's Climbing Holds Set Alphabet 26 climbing holds with all letters. The set includes 26 medium-sized climbing holds. The letter design offers a variety of shapes such as small holes, edges, small grips, and pinch holds. This set is ideal for children and is particularly suitable for use on climbing walls in schools or kindergartens, as well as in physiotherapy and occupational therapy practices. It is perfect for playfully learning the alphabet, e.g., as a complement to the Climbing Holds Set Numbers. For attachment to wooden panels (with some space behind the panel), in addition to T-nuts, 26 pieces of grip screw M10x50 are required (screws and nuts are not included).
