Duct Tape 2019 Test: Which Brand Wins?

In our 2019 test we compared 9 duct tape options head to head. T-Rex came out on top. See the measured results, the runner-up, the budget pick, and a link to the full test video. Shoppers cross-shopping heavy duty duct tape, white duct tape, black duck tape and black duct tape land here for the head to head that settles it.

The measured results

Every number below is read straight from the test. Products are listed in the order they finished.

TensileStrength(5 samples, lb pulling force)

  • 1T-Rex Brute Force

    first attempt 250 lb before the tape broke free from the metal anchor (not a tape failure); reinforced and retested at 278 lb before slipping; reinforced again and reached 442 lb without breaking (test halted); a separate purpose-built test jig later measured over 450 lb to rip the tape in half, the strongest of all products tested

  • 2FiberFix 10x

    only 2 of 5 samples run, tester stopped early for reliability/time reasons: 221 lb then 227 lb; summary rounds this to "a very respectable 224 lb", second-strongest tensile result behind T-Rex Brute Force; described as highly elastic even after failure begins

  • 4Gorilla
    106

    106, 108, 106, 103 lb (103-108 lb range); tape itself ripped, not an adhesive failure

  • 5Gorilla Weather
    105

    101, 102, 102, 101 lb (101-105 lb range); adhesive let go before the tape itself ripped on the first attempt, requiring edge reinforcement to get a valid reading; noted as more elastic than regular Gorilla

  • 6T-Rex
    101

    105, 106, 101, 106 lb (101-106 lb range); narrator notes the tape seems 'really sticky'

  • 7Duck Max
    71

    70, 69, 69, 71 lb (69-71 lb range); packaging includes an on-box strength meter shown maxed out

  • 8Duck
    44

    48, 48, 47, 44 lb (44-48 lb range), the weakest tensile result of the 8 core products tested

  • 93M Pro Strength
    62

    63, 63, 62, 61 lb (61-63 lb range); narrator notes more elasticity than Duck Max despite lower peak force

  • 3FiberFix wrap
    not tested

WrapStrength(pipe test)

  • 1T-Rex Brute Force

    not tested in the pipe-wrap event

  • 3FiberFix wrap

    soaked in water about 12 seconds, wrapped tightly around the pipe, cured overnight; held to the very end of the pipe at the initial 25 lb load without breaking; retested with 35 lb (still held to end of pipe) and finally 45 lb, failing with a tear at 29 inches out from the base, described as 'totally destroying the competition'

  • 4Gorilla

    sideways force caused the tape to split; exact inch/lb failure point not narrated in the transcript, but the video's own chapter metadata lists 'Gorilla: 8 inches'

  • 5Gorilla Weather

    stretched beyond providing structural support rather than ripping outright; exact inch/lb failure point not narrated in the transcript, but the video's own chapter metadata lists 'Gorilla Weather: 6 inches'

  • 6T-Rex

    adhesive (not the tape) failed at 9 inches out from the base

  • 7Duck Max

    failed at 8 inches out from the base at a 25 lb load

  • 8Duck

    failed at 8 inches out from the base at a 25 lb load

  • 93M Pro Strength

    failed at 9 inches out from the base at a 25 lb load

  • 2FiberFix 10x
    not tested

Adhesive Showdown(tournament)

  • 1T-Rex Brute Force

    lost round 1 of the bracket, slipping at nearly the same time as Duck Max (tied for first out of that 4-way heat)

  • 2FiberFix 10x

    lost round 1, third to lose grip (after Duck and 3M, before T-Rex)

  • 4Gorilla

    lost round 1b (heat with Duck Max, Gorilla Weather, T-Rex Brute Force), third to lose traction, beaten by its own Gorilla Weather sibling

  • 5Gorilla Weather

    won round 1b (beating Duck Max, Gorilla, and T-Rex Brute Force), then lost the final to T-Rex at a 15 lb load after an initial back-and-forth

  • 6T-Rex

    won round 1a (beating Duck, 3M, and FiberFix 10x, never budging), then won the final against Gorilla Weather at a 15 lb load; tournament winner

  • 7Duck Max

    lost round 1b, tied with T-Rex Brute Force for first to slip

  • 8Duck

    lost round 1a, first to slip

  • 93M Pro Strength

    lost round 1a, second to slip (after Duck, before FiberFix 10x)

  • 3FiberFix wrap
    not tested

ValuePerPenny(lb tensile strength per penny per foot)

  • 1T-Rex Brute Force
    23

    the best value of any tape by this metric

  • 2FiberFix 10x
    13

    tied with Gorilla for second-lowest value

  • 4Gorilla
    13

    tied with FiberFix 10x

  • 5Gorilla Weather
    8

    the lowest value of the seven brands measured by this metric

  • 6T-Rex
    16

    second-best value after T-Rex Brute Force

  • 7Duck Max
    14

    tied with 3M Pro Strength

  • 93M Pro Strength
    14

    tied with Duck Max

  • 3FiberFix wrap

  • 8Duck

WeatherExposure(~1yr, prior video samples)

  • 1T-Rex Brute Force

    not part of the weathering segment (used for the tow-strap demo instead)

  • 4Gorilla

    after about a year of weather exposure, did not hold as well, adhesive underneath became extremely brittle and crumbling

  • 6T-Rex

    after about a year of weather exposure, held up very well, still glued strongly, required a lot of force to peel

  • 8Duck

    after about a year of weather exposure, did not hold up well, described as 'not a whole lot left'

  • 2FiberFix 10x
    not tested
  • 3FiberFix wrap

  • 5Gorilla Weather

  • 7Duck Max

  • 93M Pro Strength

Tow Test

  • 1T-Rex Brute Force

    successfully towed a heavy tractor up a slight grade using only the tape

  • 2FiberFix 10x

How it was tested

  • tensile pull-strength test (5 samples per tape, upward force in lb to rip the tape in half)
  • pipe-wrap strength test (25 lb progressive load, inches of pipe supported before failure)
  • adhesive showdown tournament (10 lb plate on a tilted table, single-elimination bracket)
  • approximately one-year weather exposure adhesion test (carryover samples from a prior video)
  • tow-strap test (towing a tractor)
  • tensile strength value per penny per foot

Regarding the best all-around duct tape, I would have to say that my favorite is T-Rex.
