Animation of how the Grippa works

1. Grippa has been designed to attach to the bottom flange of the horizontal I beam. The clasp end should be presented to the furthest edge of the beam.

2. Then the holding of the webbing strap in line with the bottom of the beam, a steady pull will bring the flange grip onto the nearest edge.

3. The border cord and selvedge are placed into the hook. The hook will swing in the direction of the net. The opposite side of the net is attached in the same manner.

4. When installing adjacent nets the second hook can easily be located through the fitted net and attached in the same manner.

The Grippa has been designed to suspend safety nets beneath horizontal steel beams. It has been independently tested in accordance with the dynamic load requirements of BSEN1263-1 and provides a safe secure means of attachment.

Rigging Notes

Always ensure that the nets cross over beneath the beam. Loads will always be applied to the metal parts (the webbing strap is simply to hold the device onto the beam). Although maximum rigging centres of 2.5m can be used, in practice to avoid wasting of the net 1.8m centres are recommended. When gathering the net to take out excessive sag each strand should be looped into the hook. Dropping from height may distort the metal parts and cause abrasion or cutting of the webbing.

Limitations of use

22mm Grippa

  • Minimum flange width 150mm
  • Maximum flange thickness 22mm

50mm Grippa

  • Minimum flange width 200mm
  • Maximum flange thickness 50mm
  • Minimum flange thickness 20mm

It is important that these dimensions are adhered to in order to prevent detachment of the Grippa.

Product Examination

The equipment must be visually examined before installation. Particular attention should be directed to the following points when carrying out the examination:

  • WEBBING. Check for cuts, tears, abrasion and damage caused by gradual deterioration. Slight damage to the outer fibres or an occasional torn yarn may be considered harmless. It should be borne in mind that in normal use the webbing strap will not come under load.
  • METAL PARTS. Check for distortion, rusting, operation of the clasp and damage caused by general deterioration. If in doubt withdraw the equipment immediately from use. If the equipment has been used to arrest a fall or if it is thought to have been used to arrest a fall it is essential that the equipment is withdrawn from use. Subsequently it should be returned to the manufacturer for evaluation.
