Polargy, Inc. has added the PolarPlex P2 sliding door to its suite of data center containment solutions. The PolarPlex P2 allows data-center and facilities managers to avoid the error-prone task of measuring racks of varying sizes and ordering doors to fit. The flexibility of the door ensures that the door is always in stock, shortening lead time. The 54-in. wide P2 door covers most four-foot aisles, and side extender panels can expand the aisle-width coverage up to nine feet. The door and side extender panels are adjustable in height from 79 to 89 in. Auto-close is standard on the doors, and a “hold open” kit is available and installs in seconds. Also, the door’s insert is field replaceable, making repairs quick and easy.
