Moerman products have undergone more than a century of research and development since 1885. Moerman continues to be one of the leaders in window cleaning tools. It is performance-based, ergonomic, durable, and delivers quality with price. Choose from the Ergonomic Squeegee Handle and the Swivel Zero Degree Handle. Both options have a quick release feature. This allows for fast and easy channel changing. The pivoting head of the swivel design allows the handle to lock into a 0 degree position and a 40 degree position. Window Cleaning Resource also carries Moerman channels.
