FIBERGLASS HOLE FORMERS

Press-Seal Fiberglass Hole Formers are designed to make precise entry holes in concrete structures.  Made with fiberglass cloth (rather than chop), they include heavy wood bracing and feature a smooth, low-taper surface for easy release.  Fiberglass Hole Formers are available for manholes, straight wall structures, and for offset holes in lift stations and wet wells.  Sizes from 8" to 56" diameters in a variety of wall thicknesses.  Also available with high-strength magnets for convenient mounting to form cores.
