The Ace LED Troffer Flange Retrofit (TFD) is a high value product that modernizes an existing troffer. The TFD ships completely assembled and ready to install inside of an exist-ing troffer and is the perfect solution for hard lid ceilings and surface mounted fixtures. After installed, the TFD sits against the suspending ceiling. Unlike many troffer retrofit systems, installers love the TFD because it has fit every existing troffer encountered. That keeps projects on schedule without delays caused by products that don’t fit in the field. This DLC Premium Troffer Flange Kit is everything you need, and nothing that you don’t. When the objective is to modernize troffer lighting with universal fitment and meets your budget, let our TFD be the Ace up your sleeve.
