GR Gripper

Product description

The Gripper is a build-in detail for I-Joists into masonry providing 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
  • Air tight seal is achieved by applying mortar on either the cavity side or internal face
