100% totally American made.

Every part. Every Step.

Our new Ultra-Lightweight Food-Grade Never-Seize Manhole Assembly is innovating the industry.

Features and Benefits:

  • Up to 21 lbs lighter than industry standard assemblies.
  • Self-aligning lid gasket and redesigned lid solve a leading issue with old-style assemblies that use the metal on the lid to align to the collar, allowing metal shavings to end up in your load from metal-to-metal contact when the lid is closed.
  • Never-seize adjusters with sealed adjustment threads, protective o-rings, and a 10-year warranty.
  • Available with a composite, aluminum, or steel cam handle.
