Keep it together with our selection of tape. Duct tape provides excellent seals and seams and is a good choice for many applications. Both premium grade and professional grade are waterproof and the multi-purpose grade is an excellent general-duty tape. For electrical and plumbing jobs, we carry 3M black vinyl electrical and Teflon plumber's tape. We also have a 3M industrial tape dispenser, carton-sealing tape, DOT reflector tape and reflective marking tape.
