Pine Insulation Plugs

Our Pine Insulation Plugs are American made from kiln-dried White Pine. They all measure 3/4" thick and are slightly tapered for easy installation. Another great feature is that the top 1/8” of the plugs are straight, not tapered, to ensure a tight and even fit. Available in diameters ranging from 1” to 3”. The package quantity is listed next to each diameter below.

This product is made to order and may have a 2-3 week lead time before shipping.
