DT17 Heavy Duty Duct Tape

Constructed with a polyethylene film laminated to cloth using a natural rubber adhesive, this ultra-thick tape resists curling and tears cleanly off the roll, even in the most demanding applications.
The 3M™ Extreme Duty Duct Tape DT17 is engineered to deliver maximum strength and long-lasting performance for the most advanced applications.

A Tape for the Toughest Jobs
Originally developed for heating, ventilation, and air conditioning (HVAC) applications, duct tape is now widely used in various maintenance, repair, and construction settings. Thanks to its unique design and pricing, 3M™ Extreme Duty Duct Tape DT17 is considered the top choice for jobs requiring the thickest tape. It can be applied at temperatures as low as 40°F and withstands temperatures as high as 150°F for up to 30 minutes.

The 3M™ Extreme Duty Duct Tape DT17 is exclusively available in black. Despite being the thickest duct tape in the 3M lineup, its polyethylene backing can be torn off the roll and instantly applied. It adheres firmly to many surfaces, including plastic, glass, and sealed concrete. This makes it ideal for tasks requiring wear resistance or surface protection.

Designed as part of the 3M family of durable cloth and duct tapes, it sticks to most surfaces for a range of applications, including bundling, waterproofing, sealing, splicing, reinforcing, and hanging poly sheeting. Available in various thicknesses and strengths, these tapes are best known for their hand-tearability, high tensile strength, and conformability.
