SMOKESABRE is a major step forward in the design of smoke detector test aerosols. When extended, the patented design more effectively vaporizes the aerosol, providing better detector activation, while using less gas per test. Plus the Sabre prevents the aerosol from being sprayed too close to the detector, solving the issue of residue build up that plagues other brands of canned smoke. SmokeSabre contains no silicone, is UL listed, and uses a biodegradable plastic, making it both recyclable and eco-friendly. 2.6 oz aerosol.
