Who doesn’t have a problem with corrosion around hand holes?

You clean the hole, then coat the hole. You wait for the paint to dry, then add another coat, then wait for the 2nd coat to dry – which it never does completely. You install the hand hole cover, and the gasket invariably sticks to the tacky coating.

Doesn’t it drive you NUTS?

Now it’s time to take a potential reading, so you remove the hand hole cover… but surprise! The gasket is stuck, and you damage the coating getting it off.

Finally, we have a solution – created by an engineer, for engineers like you…

The Hand Hole Liner Grommet

Just caulk it up and fit it in, and you’re done! You’ll never have to paint that hole again.
