T-bars are essential tools for any professional window cleaner. Weight and durability are two important considerations when choosing a T-bar. Enjoy T-bars from brands such as Ettore, Moerman, Pulex, Sorbo, Unger and Wagtail. T-bar sizes will vary on the specific brand. Most are available in standard sizes: 10 in, 14 in, 18 in, and 22 in. Some T-bars feature an ergonomic handle for more grip and control. Other types operate on a swivel design or are ideal in pole work. Certain T-bars also come in a variety of colors as well. Pro T-bars, for example, come in blue, purple, black and grey. Replacement washer sleeves are also available.
