Tube Brooms are used on sweepers as a one-piece, one time only replacement instead of the individual wafer setup. The tube broom is constructed on a steel core with a steel channel where the filament (bristles and/or steel wire is crimped then spirally wound throughout the length of the tube. Other names for the tube broom can be main broom, pickup broom, belly broom, etc. For “off-label” usage these can be made into cattle scratchers which are much appreciate by the herd.
Keystone has engineered their bristles to have more filaments so the customer can have a longer life, a more thorough collection, and to have greater results in their sweeping.
The All Poly filament (bristle) is for General street sweeping where as the Poly/Wire Combo is for a more versatile sweeping.
