The Flexible Alternative

For a pliable alternative consider our line of vinyl Plus Plugs.

  • Flexible vinyl material provides a secure fit.
  • Easy to install and feature a lip for quick removal.
  • Adapts as it is placed into a hole.  As pressure from the insertion process is released, the flexible vinyl material expands inside securing a tight fit.
  • Will not crack, split, or shred over time.
