Made in the USA and UL/ETL Listed for use with APC Duct Detectors, distribution centers and installers alike will find these tubes much more convenient and easy to handle.
The tubes are fitted to the detector with a connector that is included with every detector - never walk out with the wrong type of tube.
One bag of tubes will fit duct widths up to 8ft; any spare sections are convenient to save and use on the next job or pair two packs for wider ducts.
Lightweight composite material is rated the same as the detector housings, a red fitting strip securely holds multiple sections together with no fear of tubes vibrating apart over time.
Putting them together is as simple as APC: Assemble to length, Prep by affixing the starter from the detector hardware kit then Cut and Cap to final length.
