How To Make A Brake For Your Zip Line

Zip Lining

Zip Line Setup

Zip lining is a great way to boost your adrenaline without physical activity, and one of the favorite ways to have good fun. It works on the principle of gravity, pulling the rider towards the end of the run. A good zip line brake is what lets them control the speed so they do not hit a pole or tree at speed. This post details the steps to build your own zip line brake at home.

Materials required

  • 2 zip ties
  • Two 6 x 6 x 1 blocks of wood
  • Two 2 ½ -3 inch bolts
  • 20-30 ft. of ½ inch bungee cord (based on the speed)


  • 1 large screwdriver
  • 1 small bar clamp
  • 1 wrench
  • 1 eye loop
  • A hammer
  • A ladder

Fixing up the block

Cut a slit in the wood, making this a just a bit bigger than the thickness of the cable. Do the same in the center of the other block.

Fixing the Knot

The drill can be used to make a hole in the wood, which will hold the knot. If you need to go through the wood, start a similar hole in the other block as well. This will let you fix the knot without a gap. Then use the dado and put a ½-inch slit, which is for the bungee in one of the blocks. If you want, you can get a zip tie around the knot, if you are scared about it coming loose.

Zip Line Brake Construction

Arrange the wood blocks and drill holes, which are big enough for bolts. Put one in each corner.

Bring the zip line brake together

Find the spot where you can reach the zip line most easily. If it is too high even here, use the ladder at the end where it is tied lower. Put the knot in the knothole and then do the same with the able. The top piece should be put on, and then you need to Use the clamp to hold it while it is bolted to the bottom piece.

That was on how to build your own zip line brake at home. Make sure to bolt it as tightly as you can, so that there is no wobble to deal with when you are actually zipping on the line. If this looks to be too much at any point, just go with a premade option instead, because safety is not something you want to be experimenting with.
