- The NSH-L is installed usually on horizontal blocks. This model has the flat screw bolt with no tooth. The NSH-L has three ㄷ-shaped grooves in the screw hole of the body so that even a painted bolt/ paint-stained bolt can be easily tightened and loosened.
How to use
Insert the frame flange into the end of the clamp's jaw opening and then completely tighten the screw.
