I have 164 liner feet of no clog gutter filter for sale. It is an exterior grade poly urethane foam that is cut to fit in 5" "K" style gutters.It works very well. Keeps debris out of gutters and helps to reduce ice build up in winter. Has bio-cide and UV protection built in at the manufacturer. You will get years of protection out of it. It is the same material as Gutter Filter, Gutter Stuff, and other poly urethane foam gutter filters. I will sell it for $2.00 a liner foot and pay for the shipping myself. Call me 800-650-9733. It will answer Town & Country (which is my company). Leave me a message if I am not there. I will call you back.
