Pitch Pockets are flanged, open-bottomed, metal containers, placed around columns or other roof penetrations. They are filled with hot bitumen or flashing cement in order to seal the joint, thus blocking penetrations of the roof.
Pitch pockets are easy to install. You can simply open it up and wrap it around the roof penetration. All that is required is some light hammering to the corner lock in order to hold it together. This quick installation provides a water tight seal.
B&B Pitch Pockets are available with or without soldered corners.
