crp0041-plugs-plastic

9/16″ x 1-5/8″
Available in black only…ran out of Tan and Brown to find they’re no longer made.

These are similar to the black plastic plugs that come with the 10 pack. They’re designed to be used with 1/2″ rods…either Cobra or Impel/Bor8 brands

Plastic plugs, also called “capping plug” are designed for removal and post re-treatment as the borate rods last, on average, between 3 and 10 years.
