The "C" section is forged of a steel alloy that is not subject to ageing. It is quenched and tempered up to a tensile strength of 1000-1100 N/mm². The inside of the bow is induction hardened for extra wear resistance. The "C" section has been accurately machined, so that exchange of parts is possible.
The locking piece closes the "C" section. A spring-loaded bolt can be operated swiftly with the key secures the locking piece. The locking piece has these parts:
- The forged transmitting Body, which is forged of steel that is not subject to ageing. It is quenched and tempered up to a tensile strength of 800-1000 N/mm²
- The locking mechanism, which is made of high-tensile CrMo steel. It is sealed to prevent the Ingress of dirt and Lifetime lubricated with a compound lubricant
- The spring-loaded 10 mm inside hexagon bolt, which is fully countersunk in the body
The key has a 10 mm hexagon tip that fits in the inside hexagon bolt of the locking piece. The handle is big enough to exert a rotating as well as a pressing force. One side of the handle has a chisel point to clean the inside hexagon bolt if necessary. The other side of the handle has a hammer.
