Slide into unparalleled performance Telescopic packages are desirable for their ability to maximize door opening space by 33%. Besam's patent pending equal leaf design stretches this concept even further to provide the largest clear door openings in the industry ... even packages equipped with positive latches and trackless design! Besam also improves upon the traditional telescopic experience with a unit that features an internal transmission ... allowing active leaf #2 to travel at half speed. This eliminates the "grab and bang" of other systems and makes opening and closing smooth, simple and unnoticeable. Smoke rated packages certified to UL1784 are available with t-slotted seals, concealed sweeps and positive latches.
