The gripNlock Sewer Cap
The Grip-N-Lock, watertight locking Nylon sewer cap is hammered in place either above or below grade.  It's held secure by 10 internal watertight concentric rings, and the square UV Protective Gasket creates a watertight compression seal.  All of our caps have embossed lettering with the word SEWER, and the capability to be padlocked or zip tied for security. 
                          
  • The Cap is only 3” tall when installed.
  • Recommended by several State and County regulatory agencies.
  • Easy Installation, Watertight Security, Locking Capability, and High Visibility.
  • Inexpensive Cap, "EDP Feels Anything More is Money Down the Toilet".
  • Optional Internal Threads for RV Hook-Up.

This hard-hitting Nylon Cap is built for the worst environment, easy installation and cost efficient.  This cap does not require screwing, riveting or gluing, “JUST HAMMER IT ON”.
