Edelrid Mega Jul

5   |  

The Edelrid Mega Jul is a durable and versatile, stainless steel abseil and belay device.

The Mega Jul combines features from a number of other belay devices and rolls them up into one (currently) fairly unique package. Due to its 2-rope capacity and low weight the Mega Jul will be of most interest to trad climbers.  The USP is the auto locking function which both reduces the chance of a belayer dropping a leader in the event of a fall, and makes it easier to lock off a leader if they are working (or dogging!) a route.

Once the device has locked the plastic coated thumb catch is used to unlock the rope and lower the lead climber if required. The thumb catch is also used to hold the device in the ‘open’ position meaning that rope can be rapidly paid out whilst belaying. As with other devices of this type this does take a bit of practice to master so that the leader does not lock the device by taking in rope to make a clip, which is never good.

As with the Petzl Reverso and Black Diamond ATC Guide the Mega Jul can also be used in guide plate mode, which is especially useful if bringing up 2 seconds. The small hole will also accept the nose of a carabiner so that the device can be unlocked in this mode to lower a second. It’s worth noting that the hole is too small to fully thread the majority of carabiners but using just the nose should work fine.

Because of the number of different features of the Mega Jul it is well worth watching the product video which gives a pretty comprehensive run-down of the different operations.

excellent device. I have used it for trad (half-ropes), and sports climbing both indoors and outdoors. I would not go back to an ATC. It is especially good if you climb with someone fairly heavy who has a propensity to hang on the rope for considerable pe

The Mega Jul is a great piece of kit. Not necessarily intuitive, (well I had to read the instructions, you might not), but once you get the hang of it it's great. My only caveat is that the rope diameter it works with. Using it with a 9.5mm single was di

I had been looking for a lightweight belay device that locks off so that I did not have to hold my heavier than average climbing partner with my hands as he worked out moves on steep rock. Now I have some strength left in my hands to climb after belaying!
