The UltraLite U3539-3L Wedge Pad is a 35x39x3 lightweight concrete composite equipment pad designed specifically as a base support to fit the unique footprint shape of Lennox condensers. UltraLite is strengthened by a fiber-cement coating which also provides excellent resistance to cracking or breaking. The concrete outer skin and EPS foam inner core provide flexibility and vibration dampening. The solid bottom provides excellent resistance to settling.
