Mutual Industries Closed Cell Foam Backer Rod 1/4" or 1/2" x 100 Feet, Caulk Filler Rope. Brand-new and works great. We just bought too much for our log home chinking, so we're selling in 100' increments.

We like to have both sizes on hand, the 1/4" for smaller cracks and the 1/2" for larger ones. So we thought we'd offer both in one listing so you can get as much as you need of each.

Flat-rate shipping, and discounts if you buy more than 100', so buy as much as you need. Mix and match the 1/4" and 1/2" diameters to save up to 20%.
