  • Washers are built into the relief cut section to prevent them from falling off. This also eliminates the need to mount washers.
  • The outside diameter of the washer is about 3 times the screw diameter. This provides a sufficient seating surface for the tightening area.
  • The zinc die cast serration ring is inserted into the plastic lever main unit. It achieves sufficient fitting strength with the metal screw serrations.
  • The lever is available in 3 color variations. They can be selected by the end symbol of the part number.
