This is a 1-quart size caulking gun for use with OSI SC-175 Draft & Acoustical Sound Sealant in tubes. This is a larger size than the 1/10 gallon caulking guns used for most household projects. Any 1-quart size caulking gun will work with the tubes.
The panels have really helped alleviate a lot of the reflective sound issues and visually "warmed up" our Sanctuary. - East Side Community Church More reviews and photos...
