Edelrid designed the Mega Jul belay device to work perfectly with the HMS Strike FG locking carabiner, and the Mega Jul Belay Kit includes both so you're ready to belay your partner whether you're climbing single pitch sport or multipitch trad. Edelrid made the Mega Jul belay device out of stainless steel to virtually eliminate abrasion and wear for excellent longevity so you can belay with these beauts for a long time. Use the versatile Mega Jul belay device for belaying lead climbers, belaying a second or third follower from the anchor, lowering top rope climbers from the anchor, rappelling, or abseiling. The assisted braking thumb loop the colored section gives you more control when you're lowering or rappelling. The large steel loop on top attaches to anchors so the device can lock up without your brake hand drink some water, enjoy the sights, or manage your rope while your second or third top ropes to you. Edelrid also added a small eyelet so you can lower your top rope climbers directly from the anchors. The HMS Strike FG locking carabiner features an H profile construction to keep it super strong despite its light weight. The spring bar holds the Mega Jul in place to prevent cross loading, and the keylock nose prevents the rope from snagging when you take your climber off belay. Its screwgate lock prevents the gate from opening when you're in mid belay.
