Three Phase Transformer Flat Pads

There are numerous Fibercrete® flat pad sizes available to support three phase transformers.  The pads listed below have waffled bottoms, but solid bottom pads are also available. Besides decreasing pad weight, waffling out the bottom surface of the pad aids in field leveling during product installation.   If you want a solid bottom pad number, then just add an SB to the part number. For example, use the FPSB-58-70-5-1646(12) for a 58 inch x 70 inch solid bottom pad.  The list below is a small compiliation of some of our most frequently ordered pads, but many other sizes and opening configurations are available upon request.  We offer other customization options including clamps, toggle nuts,threaded inserts, and unistrut.
