Traditionally, ABS plastic has been used for the production of clamping blocks, with corresponding resource and environmental impacts. Now, however, it has been possible to achieve the extremely low tolerances for clamping blocks with regard to a really good clamping force using naturally renewable material. Clamping blocks are milled from beech wood, which are absolutely compatible with the blocks from traditional manufacturers. OPEN BRICKS has developed exciting promotional items from this, with which companies and institutions can make a strong sustainability statement.
