Greenlee 39278 3 Brush-Wire (39278)

Using the Greenlee 39278 is a breeze. First, insert it into the duct. Thanks to its flat steel bristles, it can clean sand, grit, and light blockages effectively. You can use it in either direction because of the pulling eye on one end and the smaller twisted eye on the other. If there's dried material in the duct, pull the brush - wire to loosen it before using mandrels or spreader swabs. When using it, make sure not to exceed its maximum rated capacity of 200 lbs. For maintenance, after each use, clean the bristles to remove any debris. Store it in a dry place to prevent rusting.
