Installation

  1. Ensure the subfloor is clean, dry and structurally sound.
  2. Position the profile in its final location and use the pre-drilled fixing holes as a guide to mark the substrate.
  3. Remove the profile and drill the marked positions using a suitable drill bit for the substrate.
  4. Insert appropriate wall plugs where required.
  5. Position the profile and secure using suitable No. 6 countersunk screws. Do not over-tighten.
  6. Where fitting carpet, trim the carpet edge neatly and tuck it into the naplock section, ensuring the gripper securely retains the carpet.
  7. Check that the profile is firmly fixed and sits level against both floor coverings.

Profiles are supplied with a protective film applied to the visible surface. Leave this in place until all installation work has been completed.
