Available in Black, Brown, Weathered Wood and Gray to match your shingles. Made in the USA.

Rated 2.5 out of 5 by 2 reviewers.
Rated 1 out of 5 by Does not comply to the plumbing code. The plumbing code calls for a minimum height above the roof of 18" and max of 24" for the plumbing vent. This unit looks like it would seal well but it is only 12". October 24, 2014
Rated 4 out of 5 by I haven't used them yet but they look like they will work. Will let you know in 20 years. Product looks as advertised. Will not really know till its been on the roof for a few years. But does look like it should last a lot longer then the standard rubber boots. Ad should show that you have to silcone them as part of the installation. July 10, 2012
