T-Bars are basically handles for microfiber scrubbers that can be attached to any standard extension pole. Most T-Bars today are of the swivel type, which makes fanning windows easier than doing it with a straight neck T-Bar. It is made of aluminum or plastic and has a screw that allows you to loosen or tighten the pivoting mechanism.
T-Bars are especially convenient when cleaning high glass windows. The swivel turns to its side and conforms with the surface, so you will not make any necessary adjustments from the ground.
Most T-Bars are available in standard sizes: 10-inch, 14-inch, 18-inch, and 22-inch.
