leashes suck. but theres 2 things that suck more; dropping a tool into the void where you cant get it back, and dropping a tool into the void where it hits someone else.
its training season which means its not about giggles, its about work. there are things to be acheived and that means doing stuff that doesnt always work and tools get dropped. the current project location is a longish roof/lip that sits in a tier above a 30m face thats very popular, and which also means dropping a tool is either a pain in the ass or potentially fatal to people below. so, hot on the heels of the already talked-about top rope belay system, is this leashless rig. most set ups have ‘biners and junk that get in the way, and most tools have less-than-perfect interfaces for leashes but this solves much of that. really, its like no one has put 2 and 2 together on this. add to this the way leashes twist around each other and theres a matrix of problems that never seems to get resolved. it annoyed me like it does many others, but function demanded a result and having a rack of leashes i sorted it out.
simple, elegant & functional
those are Blue Ice Boa leashes hitched to the swivel and hitch sling from a Black Diamond Double Springer. the Fusions (reknowned for having dubious attachment options) simply have 2mm cord hitched around the pommels with loops hanging off. the loops from the Boas hitch into these, via looping over the head of the tool. no little biners, no drilling into metal, nothing requiring tools beyond the scissors to cut the Springer leashes off the swivel. find a better system. you can even re-rig it to the heads of the tools in seconds for piolet stuff.
the interfacing bits: nothing fancier than some girth hitches, clove hitches and double fishermans
it is expensive. you need to spend on 2 sets of leashes unless you rig from other bits. but its more than worth it if leashes drive you crazy on the times when you have to use them.
note: this rig by no means is said to support a fall. anecdotally it has, but none of the parts is rated for such
