Uprights are the next step for installation. With our guide system of bed to lower upright, or upper upright to crown make rigging and installation easy and accurate. The uprights include an 8-point full length taper wedge slide guidance system that is lubricated by recirculating an automatic oil lube system. Stainless filter screens in drip trays prevent debris from entering the system. Oil system pressure and flows are monitored via our I-PRESS control.
