There is no guessing when it comes to your dust or granular applications. The clear body on the 5 inch standard duster is made from durable clear synthetic rubber that enables you to see how much dust you are applying. This duster is ergonomically designed with low-tension springs to avoid user fatigue. The 5 inch duster also includes a removable plastic tip cover and cap as well as an “o-ring” on built-in clean out rod to help prevent dust leakage. For the best results pair this with one of our quality insecticide dusts!
