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.
- 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
