*Figures in these two columns denote Pushmepullyu Grippers and the ZF-30X2 looping gripper when used in a looped configuration. For all other configurations see regular ZF Standard weight load figures.

  • USE CORRECT WEIGHT LOAD CHART. Griplock’s ZF Standard Grippers (see 2nd chart) can be identified by the CF marking on the gripper. They have a lower SWL than Griplock Premium Grippers (see 1st chart)
  • The 5:1 SWL reflects the US Lighting Industry standard. Where no SWL is shown, grippers and cables are not compatible.
  • Chart indicates the SWL for gripper / cable combinations when used with 7×7 or 7×19 stainless steel aircraft cable. Do not use plastic coated cable.
  • Charts apply to Griplock Premium or ZF Standard Grippers only. They are not applicable to any other cable gripping product.

Angled Applications

An angled cable will reduce the weight a suspension system can hold. Angles over 60° are not recommended.

• Cables should not enter or exit couplers, grippers or tensioners at more than a 5° angle
• A pendant fixture exerts greater force on angled / non-vertical cables than it would on vertical cables. To determine the force exerted on an angled cable, take the fixture weight and divide by the number of cables. Multiply the result by the factor beneath the angle from the vertical in the chart below. If the weight per cable is 20 lbs. and the angle is 60°, the force on the cable = 20 / 0.50 = 40 lbs. Angles over 60° from the vertical are not recommended. For help with this please call our office.

Angle from vert. 0° 15° 30° 45° 60°
