Before you start

  • Confirm register size, grid module, boot neck, throw pattern, damper option, and independent support.
  • Verify the boot and branch will not load the T-bar grid.
  • Inspect register face, blades, neck, and boot for damage.
  • Coordinate tile opening and finished ceiling elevation.

Tools and materials

Lay-in supply register, matching boot, branch duct, approved fasteners and sealant, independent hanger wires or brackets, level, tape, and hand tools.

Lay it out

  1. Locate the register from the reflected ceiling plan.
  2. Set the boot and face to the grid module.
  3. Orient blades for the approved throw pattern.

Set and support it

  1. Support the boot from structure.
  2. Keep the grid free of duct weight.
  3. Support the branch near the boot.

Make the connection

  1. 1

    Set and support the boot above the grid.

  2. 2

    Connect and seal the branch.

  3. 3

    Place the register in the grid.

  4. 4

    Fasten to the boot where required.

Check the install

  • Face is centered and level.
  • Boot is independently supported.
  • Grid carries no duct weight.
  • Neck connection is sealed.
  • Blade direction matches the room layout.

Common mistakes

  • Resting the boot on the grid.
  • Using the branch to hold elevation.

Stop and ask

Stop if the register size does not match the grid or boot, the grid is carrying weight, or the intended throw pattern is unclear.
