Before you start

  • Confirm whether the door or partition is fire-rated, transfer-grille listing, sleeve depth, security needs, and door balance.
  • Inspect both grille halves, sleeve, fasteners, and edges.
  • Verify the opening does not conflict with door hardware.
  • Do not cut a rated door without the exact listed assembly.

Tools and materials

Listed or approved transfer-grille assembly, sleeve, opposed grille halves, tamper-resistant hardware where required, template, cutting tools, edge protection, and hand tools.

Lay it out

  1. Mark the opening from the approved door elevation.
  2. Check hinges, lockset, closer, and vision-panel clearance.
  3. Align both grille faces.

Set and support it

  1. Support the door during cutting.
  2. Install the sleeve so it does not distort the door.
  3. Keep the assembly centered.

Common mistakes
