Kozy Kollar

Anyone familiar with this product (plumbing vent collar)? Wondering how well it seals with architectural shingles.


I can’t imagine it would seal very well at all. It appears to rely on some sort of sealant described in #2 of this link: http://www.kozykollar.com/Installations/installations.htm

Seen one this weekend Larry on a Flyby Inspection I did for a Bank.

Can’t say how it performs, but seems to be the going thing on new construction.

Me, I will take the old conventional boot. ;):mrgreen:
