Note:
The light-duty screw jack was designed for clamps with slot-sizes up to 14 mm. Medium-duty screw jacks match clamps of slot-size 14 to 22 mm. The screw jacks no. 6430 are useful completions for large clamping heights. Heavy-duty screw jacks match clamps of slot-size 20 to 40 mm. The screw jacks no. 6435S are useful completions for large clamping heights. When using clamps DIN 6315 B, 6315 C and 6315 GN with slot-sizes above 26 mm we recommend the locating pad no. 6443 for safety. Extra-heavy-duty screw jacks were designed for support of large workpieces. Suitable pads for size 52-100 are no. 6440, 6441, 6442, 6443/14 and 6445. Suitable base is no. 6442. Suitable pads for size 140-300 are no. 6440, 6441, 6442, 6443 and 6445.
