Replacement bristles for the 7' Drag Broom. The 4 1/2" Coarse/Stiff Bristle is sold in 7' lengths and is designed to replace worn out bristles in either the hand or tow model of the 7' Drag Broom. However, these bristles can also replace the 6" bristles found on the 7' Drag Broom/Lute. To replace 1 row of bristles, order 1 unit. To replace 2 rows of bristles order 2 units. To replace 3 rows of bristles order 3 units. We ship the product in 3 1/2' lengths to avoid damage in shipment. Before ordering, it is a good idea to be certain the existing bristles in your broom can be removed since they can become 'frozen' in the bristle tracks.
