Make It Real: Batman Grappling Hook and Rappel Device

Batman v Superman: Dawn of Justice just came out so we decided to do some batman themed gadgets. It was a lot of fun to make and the best part is that it actually worked.

Click here for the full video playlist.

Project design goals

  • Build a working grappling hook and rappel device that will detach and wind up for reuse.
  • Functional. Batman gadgets need to be reliable; because your life depends on it.
  • Small. These gadgets must be able to be carried easily or worn on a belt
  • Aesthetically pleasing. Bruce Wayne has a lot of money to waste and requires all of his gadgets to look awesome.

We started by designing and building a clamp linkage inspired by a pallet clamp.

And then we made it bat themed…


We got this laser cut out of 1/8″ stainless steel at Ontario Laser Cutting Inc.

Next was the rappel device. There are rappel devices on the marked such as ATCs or GriGri but they are designed to use with 9-11mm diameter ropes. Ropes this large are too large for batman to use so instead, we used Kevlar rope and had to design our own belay device.

It was a little tricky and took a few iterations to get the belay device to work properly. Turns out, it is a lot more difficult to grip a 2.5mm kevlar rope than a 10mm climbing rope. This lead to some failed descents as well as some rope burn.

If you’re interested in making your own grappling hook, we sell DIY kits, and fully assembled deluxe versions on our Etsy store. Oh, we also sell Batarangs too!

    I would love to try and get my own repelling device so could you post the designs for the final version

    • Ian Hillier says:

      Sorry, the design is not final and is not completely safe so I do not feel comfortable sharing it. If you are looking to rappel, I would recommend an ATC.

  2. Mary says:

    Hello..I have a fired who is obsessed with the repeling device.. please let me know what I can buy the DIY kit with everything included..can’t find it anywhere…thanks!!!

    • James says:

      Hi Mary,

      We only sell the hook and batarangs. The rappelling device was a one-off prototype we made that cost $500 to manufacture. It is not reliable and not safe. We will never be sharing the plans or making it available for sale. Sorry!

  3. Mary says:

    I bought both items already, can’t wait to get them..Oh no.. what a bummer..you guys are extremely talented millions including myself would but it all!!!! What about captain Americas real shield??

  5. […] clamp. Cut from stainless steel on our waterjet. I I was inspired to design mine after seeing what theHacksmith came up with. It’s a hefty piece of hardware, for sure. No need to ramble, check this thing […]

  6. Simon Ro says:

    I want to buy a hook like yours. I can’t find one in the Internet. In the description of your YouTube videos you shared a link were we could buy one but when you click on it it says that the item isn’t available anymore…

    I like your videos and hope that more cool projects will follow.

    Lots of love From Germany.

    what would happen if you guys used paracord instead of the 2mm string you used. It would be 550 ibss and it has shock absorbing abilities.

    • James says:

      Well, the kevlar is rated for 1000lbs, but even with paracord’s shock absorbing abilities, it might still break. It’s a pretty high impulse — a 150lb person jumping up and down can easily exceed 550lbs pretty fast

  8. Nino says:

  9. Shawn says:
