Title: GREAT TO CONCEAL SPEAKWIRE
Review: I used this to route a trough up my wall to conceal speak wire to my home theater speakers. It worked like a charm!!! My house is 1955 with plaster/mortar walls. I also used the dust extractor adapter - What a charm ABSOLUTELY NO DUST!!! If you have a Rotozip and a dust problem you need the dust extractor!!!
