The SD-T60 is a 60-inch rigid air sampling tube for Kidde SuperDuct duct smoke detectors. It replaces worn or damaged sampling tubes on existing installations and extends coverage to ducts that need a longer reach than the standard tube. Drop it in from the front or back of the housing, rotate in 45-degree increments to align with airflow, and the job is done.
Built for the commercial installer
Compatible with the full Kidde duct detector lineup: SuperDuct four-wire (SD-4W series), two-wire (SD-2W series), intelligent addressable (FX-PDD), and Intelligent Optica models. Standard sampling tube hole spacing matches existing duct cutouts, so this drops into a prior-generation detector replacement without modifying the ductwork.
Key features
- 60-inch reach for wide or deep duct runs that exceed standard tube coverage
- Front-side or back-side mounting with 45-degree rotational alignment to match airflow direction
- Drop-in compatible with SuperDuct SD-4W, SD-2W, FX-PDD, and Optica duct detectors
- Standard hole spacing for direct replacement of existing sampling tubes without duct modifications

What duct detectors is the SD-T60 compatible with?
Compatible with the full Kidde duct detector lineup: SuperDuct four-wire (SD-4W series), SuperDuct two-wire (SD-2W series), Intelligent addressable (FX-PDD), and Intelligent Optica duct detectors.
Can I install this from the back of the duct detector housing?
Yes. The sampling tube installs from the front or back side of the housing and rotates in 45-degree increments for proper airflow alignment.
Does the SD-T60 fit existing duct cutouts?
Yes. Standard sampling tube hole spacing matches existing duct penetrations, so you can swap in the SD-T60 without modifying the ductwork.
When should I use a 60-inch tube instead of the standard length?
Use the SD-T60 on wide or deep duct runs where the standard-length sampling tube doesn't span the full cross-section. The longer tube ensures representative air sampling across the entire duct width.
