We all know that rappelling is the most dangerous part of climbing. With Beal’s Jammy Prusik, you don’t have to leave anything to chance. Beal created the Jammy with the fear of botched knots and your safety in mind. Constructed from rope with a nylon sheath and aramid core, this sling weighs just under an ounce but adds an extra element of safety to your climbing day.
The Jammy’s recommended prusik knot is a Machard, but this sling can also be used to create a speedy rope clamp for swift hauling. The rope’s material resists heat and damage from friction and is supple enough to grip thinner rap ropes. While the Jammy’s purpose is to up the safety for rappelling or hauling, this sling would not be a wise device to whip on or weight with gear.

The short one is always on my harness as my autoblock/prusik. This is rated to 22KN, so unlike a 5mm cord, you can use it as a sling in a pinch. I had to construct a trad anchor with limited gear and used this to basket a chock for a bomber first piece. Dump your 5mm cord and add one of these to your harness.

Pretty simple piece of gear. Not much to it but works. The rope is easy to work with and catches pretty well. I normally use a hollow block for backing up rapels but switch to this as itâs a little thinner and just looks cleaner and easier to see if itâs dressed properly.

I'm using a 9.7 mm rope and want to use a Prusik for double strand rappelling. I cannot find any recommendations for how long I would want my sewn prusik chord. I even bought the 8mm Bluewater one and found it is only long enough for a single strand. What length is recommended?

Hey Collin! I actually recommend using this: BWR0018 to make your prusik loops via double fisherman's' knot. It is a lot easier to buy accessory cord and use a rope-cutter to get the exact length you need to make prusiks for various uses. However, I would suggest a length of 70cm to 1m of material for a double-stranded rappel.
