Size:24 mm x 54.8 m Product Description Constructed of water-resistant polyethylene film laminated to cloth with a rubber adhesive, 3M Heavy Duty Duct Tape 3939 resists curling and tears off the roll cleanly for easy application in general indoor MRO/construction environments. The rubber adhesive sticks instantly and provides a tight moisture-resistant seal in many containment situations, while low tack roll edges stay cleaner. Designed for heavy-duty use, this conformable tape allows for a wide range of permanent and temporary solutions, including patching, bundling, reinforcing, tabbing, taping/splicing insulation, capping pipe, securing conduit ends, marking, labeling, temporary repairs and more. Can be used at temperatures as high as 200F for up to 30 minutes. From the Manufacturer 3M Heavy Duty Duct Tape 3939 is constructed of a water-resistant polyethylene laminated to cloth reinforcement and backed by an aggressive natural-rubber adhesive, making the tape high-tack and conformable. This tape tears easily and cleanly—horizontally or vertically—without slivering. Industrial applications include hanging polyethylene drapes for containment activities, masking, and sandblast overspray protection. It is also used in the convention industry for holding and seaming carpet padding, taping down cords and hinging poster-board panels.3M Heavy Duty Duct Tape 3939 can be used in temperatures up to 200 degrees F. It has been burn tested according to the methods UL 723, ASTM E-84, NFPA 255, UBC 8-1. Results were Flame Spread Index 0, Smoke Developed Index 30. Duct tape (sometimes mistakenly referred to as “duck tape”) is a toolbox mainstay, used in maintenance, repair and construction operations. The term “duct tape” comes from the silver tape’s original use in heating, ventilation and air conditioning (HVAC) applications, including duct sealing. Today it performs wherever patching, bundling, reinforcing, tabbing, splicing insulation, capping pipe and conduit ends, labeling, temporary repair, hanging polyethylene drapes, or protecting against light sandblast overspray is needed. Duct tape is used in residential, industrial and commercial environments and by members of construction, electrical, industrial, marine, and military, abatement, trucking and automotive markets.

The Duct Tape to Reach For When "We Have a Problem"
On one of the early Gemini missions, a minor problem developed in the capsule while in orbit. In discussing possible solutions with engineers on the ground, one of the astronauts said, "I wish I had a roll of duct tape." He was joking... but the engineers looked at each other and said, "It's a good idea; make a note of it." Before the next flight, a team of NASA material scientists, space flight experts, and engineers studied the market and selected the best duct tape, 3M 3939. And it's been on every US manned space mission since. With each new mission, they make a new study, but have consistently come to the same conclusion: 3939.This, 3M 3939, is the duct tape that famously saved Apollo 13. This is the only duct tape that NASA reaches for when, "We've got a problem."And 3939 is the only duct tape that I reach for when I've got a problem. Yes, it is more expensive, but you use less and get better results because it is a superior product. It sticks well. It conforms well. It cuts and tears cleanly. And it doesn't deteriorate and get dry or gummy as other duct tapes do. It works well and gives good results. Once you have experienced a superior duct tape, once you have seen the results and seen how a superior duct tape can help you solve problems faster and better, you will not want the cheap stuff again.

I use it as Medical Tape
This is the very best for First Aid. Blood cannot seep through like any regular medical tape. It will seal oxygen out from under neath for killing a wart, or to soften skin.

They Really do Mean Heavy Duty
This tape is designed like a tank. Very nice and strong. It resists high humidity as well.

Never go on a road trip without it!
As I told my son as he loaded his new pickup college graduation gift, heading to grad school in MO, "Never leave home without it!" Speaking of authentic 3M Duct tape. That was 1989, and it's just as true today! In 1971 I used it to repair a broken camper jack cable, so it could be loaded back onto the truck to get out of our camping area to miss the impending storm that would strand us in there! (without lengthy details) The tape held the cable together just fine. Today, my son and his family never goes on a family camping trip without it!

Best tape ever
I thought I had found great tape before. No...THIS is the stuff. I think you could hold back Superman with this tape. Get it...you won't be disappointed!UPDATE: It has been over six months. I used these on boxes in a dusty storage unit. The shipping tape I previously used often began detaching from my boxes over time but not now. I think my boxes would rip if I try to pull it off. Keep scissors handy. ;)

Heavy duty
HUGE roll of tape! I didn't realize how much tape was on this (I probably just didn't read the description well!) We won't have to buy any more for a long, long time! It is very sturdy, thick tape, but comes easily off the roll. And I received it promptly. I very much recommend this!

This stuff is great! Strong as iron
This stuff is great! Strong as iron, and good to have on hand for all kinds of emergencies. Lots of times when I buy duct tape now, its not the strong kind I remember - the stuff you could hold together a car with if you needed to. This stuff may not actually hold a car together, but it is definitely strong, heavy duty duct tape, and will handle all kinds of mishaps.

This is the duct tape you've been looking for. Welcome to Mos Eisley.
This is the real thing: strong, heavy threads, and good glue. Never buy the cheap ones; they're like a strip of trash bag with double-sided scotch tape on one side.

Silver duct tape 3939, in class of 3M
Superb as usual by 3M. They're truely world class company and this 3939 duct tape is great. May sound pricey, but when you see the quality and the quantity, it more than value for money. The tape is thin but rugged, a bit flexible hence easy to work & bind. Can be torn quite easily.

Works but a little difficult to tear off tidily
The tape does work well and it's a little more heavy duty than the normal ones, although not was strong as Gorilla tape. Tearing it off, however, proves a bit of a challenge. Duct tape usually tears off tidily but not this one. The tear does not go easily across the tape.
