This ergonomic t-bar is made with a lightweight plastic that will allow you to glide over those windows and scrub on those tough stains, without having to let your arm rest in between windows. It is designed with slots that help retain water. This way, you won't have to re-dip your sleeve/t-bar tool nearly as often as you might otherwise. Less fatigue, less dipping, more doing. What we are trying to say is that you are well on your way to becoming a window cleaning ninja. As an added bonus, this t-bar fits most pole brands and has a comfortable rubber grip to help you keep those nunchucks, sorry... that t-bar, in your hand.
