How the Vertical-Lift Counterweight Balanced System Operates

The Renlita vertical-lift system use counterweights in the jambs to effortlessly move the door. The counterweights eliminate any need for hydraulics, straps, or cables, and allow the system to have a very small motor, which is essentially used to get the door/weights in motion. Since the system is completely jamb supported, it greatly reduces the lateral load applied to the building structure, and eliminates the need for structure at the head.

Amazingly, doors up to 90’ wide x 30’ high can be provided by Renlita, and they can accommodate up to 14 lbs/sf of cladding. High thermal performing double and triple glazed windows are available, making Renlita doors the best in the industry in NFRC air infiltration and U-factor/R-value.
