Bapna duct tape is cloth- or scrim-backed pressure-sensitive tape, useful for sealing heating and cooling ducts, produced because standard duct tape fails quickly when used on heating ducts. Duct tape is generally silvery gray, but also available in other colors and even printed designs. Duct Tapes are built to stick. Whether your surface is smooth and refined or rough and rugged; whether your job is one hour or one year. Sealing PVC pipes, covering tripping hazards, repairing or hanging poly sheeting duct tapes can get the job done.
