Carboy brush. Also water bottle brush. Brush part 8 inches long, 2 inch diameter. Total length 22 inches.
Made of black nylon twisted into galvanized wire. Brush is mounted on a metal shank and attached to handle by a swivel joint permitting the brush to reach all parts of the bottle.
Hardwood handle 3/4 inch diameter and 12 inches long.
The customer may extend the handle to greater length so that it may reach to a greater depth inside the container to be washed. This may be accomplished with the use of a metal or plastic tube of the desired length fitted snuggly over the wood handle. Grau-Hall does not offer such tubes as they are commonly to be purchased from any hardware store.
