GR - The Gripper


The Gripper is used as a build-in detail for I-Joists into masonry and provides an air-tight seal at joist end. The Gripper can be used on both external and party walls.

ADVANTAGES

  • Easy to install - NO nailing required - a secure fit is ensured by the Gripper’s double hinge action.
  • No mastic is required to seal the I-Joist perimeter.
  • Does not affect the overall length of the I-Joist.
  • Mortar from outside/cavity side only.

MATERIAL
0.6 mm – galvanised mild steel - Z275


Advantages of Build-in Details requiring External Mortar Sealing only:

  • In line with existing building practice
  • Easy access
  • Quick and effective
  • Visual quality check from outside


External Wall Application
Mortar to cavity side only, to achieve air tightness performance.
Party Wall Application
Mortar to cavity side and to internal face to achieve 60min Fire Rating and air tightness performance.
