Understanding a product design means listening to customer needs and how a product functions when in use. This leads to continuous innovation like our Quick-Set™ retractable top and bottom seals that provide the easiest in-field operation. A simple half-turn of the waist-high removable handle extends or retracts the sound seals up to 7 inches as needed. Other examples include our HufGard™ safety systems and our new Hufcor Touchpad backlit LCD powered wall controller.
