Stowing brakes for BASE

Visit Us

All BASE Canopy Brake Stow techniques are the same. There is a control line, a guide ring, a stow loop, and a type of cateye or brake setting on the control line. And, of course, a toggle. Using these ingredients, you must configure your packjob for the type of jump you are about to do.

If you are reading this and thinking to yourself that an article about how to stow your brakes shouldn’t need to exist, then don’t laugh.

We have seen people get this wrong – stowing brakes without guide ring or set loop, shearing off elastic keepers, etc. Yes, people who have taken “good” FJC courses. Yes, people with mentors. Hey, it happens, and sometimes we all need a reminder or a reference or a double check. We hope this article can help people verify their packing, if in doubt.

There is no BASE jump where it is unnecessary to stow your brakes. Even unpacked jumps are better with brakes stowed. So, this is an essential step.

There is no BASE jump where it is unnecessary to stow your brakes”

This brief article can serve as a refresher, or a reference, for BASE jumpers who want to confirm their settings, but it cannot replace proper instruction from a qualified BASE mentor.

There are two basic categories for stowing brakes, Slider Up, and Slider Down (or off).

Slider Up

Use your Shallow Brake Setting (SBS). Yes, that’s the one closest to the brake toggle.

The sequence is:

  1. Control line through slider grommet.
  2. Control line through the guide ring.
  3. Then toggle tip through the cat-eye on the line below the guide ring, then toggle tip into elastic keeper.
  4. Firmly press the toggle onto the velcro and stow the excess brake line in the keeper provided.

Slider Off (or down)

Use your Deep or Deep-Deep Brake Setting (DBS). These are the settings closer / closest, to the parachute.

LRM* set: The sequence begins with the control line outside of guide ring, and outside of the slider grommets (if the slider is not removed).

  1. Pass the spectra stow loop on the riser, through the cateye on the brake line, then through the guide ring.
  2. Pass the toggle tip through the stow loop, and into the elastic keeper.
  3. Firmly press the toggle onto the velcro and stow the excess brake line in the spot provided.

Through-Ring set: In this scenario, you leave the control line routed through the guide ring, and through the slider grommets if the slider is not removed. Here, you can stow the brakes the same as when slider up, with the toggle tip through the cateye below the guide ring, and into the elastic keeper. Firmly press the toggle onto the velcro, and stow the excess in the spot provided.

Steps and Settings for Slider Up or Slider Off / Down

Should I Always Pack Deep, or Shallow, for Slider Down (off) Jumping?

The answer to that question, is in the All About Brake Settings article.


When jumping slider up, the control lines are routed through the guide rings on the risers and through the slider grommets. For slider-down (or slider removed) applications, the most popular technique in North America is to route the control lines outside the guide rings (and outside the slider grommets if it’s down, and not removed).

In other parts of the world, notably Australia and some of Europe, many jumpers leave the control lines inside the guide rings for slider down jumping. The cost-benefit analysis here depends on the probability of two events:

  1. A line-over malfunction, which can be cured by dropping a toggle if your control line is outside the guide ring.
  2. Accidentally dropping a toggle and suffering reduced control of your parachute.

Event 1 – If you are jumping in an area where a safe landing can be executed using rear-risers, and dropping a toggle accidentally is not a huge deal, then it makes sense to route the control line outside the guide rings. The cost of retaining the ability to drop the toggle in case of a line over is low, and the benefit of being able to immediately clear a line over is substantial.

Event 2 – If you are jumping in an area where a dropped toggle could mean serious injury because you need full control of your parachute to land safely (i.e. every BASE LZ in all of Australia), and you feel that the chances of dropping a toggle are greater than the chances of having a line over (for me personally this is true), then routing the control lines through the rings, which prevents the loss of a toggle, is smart.

Likely, you will become used to one or the other for slider down BASE, and stick with it. The feel and handling characteristics of a parachute with control lines routed in or out of the guide rings is distinctly different.

ALWAYS use a form of tail control, whether it is a standard tail-gate, tape, tail-restrictive packing folds, or a combination. If not using the LRM, it’s a good idea to have releasable toggles and a hook knife.

*The Line Release Modification: The LRM is the practice of routing your brake lines outside of the riser guide rings and slider grommets when jumping in a slider-down configuration. The LRM’s simple concept was conceived by Mark Hewitt in 1986.
