What Are DUT Ties?

DUT Ties are open ended elastomers with a unique (and patent pending) ability to connect to themselves (and other DUT Ties and MUTDUTs ), all made with high grade plastics and polymers in many different durometers…

In other words they’re More Useful Than rubber bands and More Useful Than bungee cords. We’ve made them a hundred times as useful so they do a hundred times as much, get used a hundred times as often and, because they’re made of better materials, last a hundred times as long.

More Useful Than Cable Ties

Cable TiesDUT Ties
Can only be used once (and are usually not recyclable)MUT Bands can be used and reused hundreds of times
Cannot adjust tightness, go too far and you can't go back.Uses elastic materials to gently encompass cables, so it automatically adjusts if you "flake out" some line or remove some cable.
Have no "give", pulling on the cable can damage the cable.Will give a bit without damaging whatever it is securing.
Difficult to remove (requires a tool, may damage cable in process)DUT Ties are easy to remove with just your hands.
Stiffness makes wrapping around an item difficult to thread and secure with one handYou can choose a stiffness ideal for the task, and much easier to thread.
"Head' of cable tie has sharp edges, digs into the uses and whatever it is securing.DUT Ties have no sharp edges.

More Useful Than Rubber Bands

Rubber BandsDUT Ties
Can only be used to bundle thingsCan bundle, secure, connect, organize and even build structures (with the stiffer models)
Break easily, made of cheap latexAre made of high end TPU
Close endedOpen and closed ended if you connect them, your choice.
Cannot be unknottedHave Loop Lock technology, so connecting and disconnecting them is easy.
Not designed to connect to anythingDesigned from the ground up to connect to almost everything, especially other DUT Ties and MUTDUTs.
Same stretchinessCome in all types, depending on your application.

More Useful Than Bungee Cords

Bungee CordsDUT Ties
Are Ultra Dangerous!No metal parts make them safer. If you need a hook you can just slide a carabineer in the last hole.
Can only be connected by latching the hooks together, a dangerous and insecure practiceUses Loop Lock technology to stay secured.
Cannot be made to breakaway safelyA single weave can be undone easily. Two or more stays securely locked.
Have only one connection pointHave many connection points so you can connect to other DUT Ties, carabineers, etc.
Metal ends dig into whatever you are securing: scratches paint on your truck, frays the coating of wires, and worse.DUT Ties are soft and friendly to surfaces and users.

More Useful Than Rope and Cords

Ropes and CordsDUT Ties
Splicing requires experience, lots of time, and a special tool, a Fid.Loop Lock technology means never needing to splice
Better know your knots! Bowline, double figure 8, Englishman's loop, clove hitch, half hitch, truckers hitch, at a minimum…Loop Lock technology means never needing to know a single knot. 3 year olds can use them.
Don’t you love trying to undo a tight knot?Loop Lock technology means never needing to undo a knot again
Don’t you love trying to untangle rope?DUT Ties are much easier to store and keep untangled. You don’t even need to coil them.

More Useful Than Tie Downs

Tie DownsDUT Ties
ExpensiveMany DUT Ties are less expensive than a tie down of equivalent length (But not strength, Tie downs are stronger)
Loose ends flap in the wind, get tangled or snagged easilyIt's easy to secure DUT Ties' loose ends.
Metal ends dig into whatever you are securing: scratches paint on your truck, frays the coating of wires, and worse.DUT Ties are soft and friendly to surfaces and users.
Are not corrosion resistant, especially in seawater or wet conditionsDUT Ties are completely corrosion resistant in all types of water, resistant to most types of chemicals as well.
Absorb water, a bucket full of them gets heavy quicklyDUT Ties are light weight, wet or dry.

How do you connect a DUT Ties?

Squeeze the ball and pull through another hole. The ball will expand back to its original size and shape. DUT Ties will hold their loop while remaining easy to adjust. If you want to keep your loop extra secure, loop the end through one more time and...

It's easy to interconnect DUT Ties, because they we're designed to work together.

Every DUT Ties has two ball sizes and the smaller ball is the same size as the larger ball on the next smallest DUT Ties. This means DUT Ties can all be interconnected together regardless of their size.

Our initial launch has four sizes:

  • 16mm ball size, 632mm / 24.88in long
  • 12mm ball size, 480mm / 18.98in long
  • 9mm ball size, 366mm / 14.41in long
  • 6.75mm ball size, 274mm / 10.79in long
