  • With bell & spigot designs you simply lube and push together, field installation is a snap
  • Unlike pipes from other manufacturers, there are no additional gasket materials, grout or sealing bands to transport and apply.
  • In-line bell design means no need to dig bell holes - and no worries about improperly dug bell holes that can dip or sag, leading to bell shear.
  • Noticeably faster installation times
  • Lower labor costs
