Bisco P is a plastic biscuit which fits into the 7 mm P-System groove and is held in the groove due to its surface structure. Bisco P is used in combination with Clamex or Tenso as a cost-effective alignment element and ensures flushness of the joint. The Bisco can also be used as a dry joint as a test before the work piece is permanently joined with Tenso P and adhesive. Bisco P-14 is used in combination with Clamex P-14 or Tenso P-14 and Bisco P-10 with the same connectors in size P-10.
