  1. H-24 Positioning Blocks : Material SUS440, 56-58 HRC. After special coating, the surface can reach 70 HRC for better wear-resistant. When the side collision exceeds 600kgs, it will be damaged for self-protection. Standard parts and available for replacing easily. Fixing screws : M4x12.
  2. Main structure : Material SUS420, 52 HRC. Eliminating the structure stress by three times of tempering for keeping same accuracy.
  3. Locking plate : Material SUS420, 48-50 HRC. With special locking design for labor saving. The strong structure can withstand clamping power more than 5000kgs.
  4. Handle : Design with proper weight. It’ll be damaged for self-protection when the force exceeds 65 kgs. Please remove the Handle after lock tight for anti-vibration.
  5. Anti-loose and Anti-clockwise structure : After removing the Lever Tool, the lock plate will ensure the stability under heavy cutting or dramatic vibration.
  6. 3-jaws type Blocks : Material SUS420, 52 HRC. Large locking area which can withstand 4000 kgs clamping force and resist the vibration by heavy cutting efficiently. It won’t get damaged even the handle is broken.
