Installation Guidance
Mounting: Before fitting the DAFA Universal Cable Grommet 115, ensure a stable base is in place to mount the wind barrier and grommet securely. This surface may be formwork or 15 mm plywood. The conduit should be firmly attached to the structure.
Installation: Affix the grommet directly onto the wind barrier. Its self-adhesive design removes the need for additional sealants, glue, caulking, or tape. This straightforward process simplifies installation, ensuring a fast and effective airtight seal.
