DUC-BLOC 20′ MINI KIT
Sierra Building Science, Inc.
For those EXTRA tall ceilings. This is a great starter kit to really appreciate how easy Duc-Blocs are to use. High vaulted ceilings, entry ways, open-to-below, stair wells. Who designs this stuff? It seems like every house has one or two registers that are out of reach of a regular 8-foot step ladder. A Duc-Bloc pan on the end of a super high quality, aluminum, 20-foot Zip-Wall™ spring-loaded pole makes these registers the easiest to seal.
THE DUC-BLOC 20′ MINI KIT CONTAINS:
(2) 12″x18″ Duc Bloc™ Pans
(2) 20 ft. ZipWall® Spring Loaded Poles
