You can trust your drains are protected with Pro-Tech!

The Pro-Tech™ Dome Lock offers a tamper-proof solution to keep scrap, debris, and trash out of the drains and plumbing system. No more calling a plumber and waiting for them to arrive.  This product will lock down floor sink drains, mop sink drains, and just about every drain in your restaurant or commercial facility!

  • Made with a super impact-resistant composite polymer. Even if you hit it with a hammer, it won't break!
  • Fully assembled one piece unit that installs in seconds.
  • The dome strainer allows water to drain freely into pipes but stops larger items from passing through
  • The lower expander catches smaller items such as mop strings
  • As you tighten the security bolt, the expanding teeth grips the pipe without damaging the inner wall of the pipe.  This won't pull out of the drain!
  • Stainless steel rust-resistant security bolt, so only the authorized personel can open the drains. (Security wrench and bit sold separately.  Please choose at least one of them.)  
  • Can withstand chemicals & hot fluids
  • Distributors - contact us for private labeling (500 locks or more)

  • Remove existing cover or dome if present
  • Insert the Pro-Tech Drain Lock into the pipe 
  • Use the security wrench tool or security bit (sold separately) to tighten down the bolt.
  • As you tighten the bolt, the lower portion of drain lock expands and locks against the sides of the pipe which prevents anyone from removing it
  • The only way to remove the drain lock is when you choose to untighten the bolt & remove it from the pipe.
