Standby generators require a level base for placement of either a concrete pad, bed of crushed stones, or a wood framed base filled with crushed stone. O.J. Mann provides either the option of a pre-cast GenPad© made to the specific contours of the generator, or a custom created pressure treated wood framed base filled with crushed stone. Our pressure treated wood framed base is ideal for locations that are on an incline and are custom built by a carpenter at O.J. Mann Electric.
