Strange, these kits used to come with the tip attachments. I guess not anymore. I bought mine a few years ago, just didn't get around to installing it until this season.
In any case, I bought this kit to replace the ClipFix system on my Ascension skins. The ClipFix system worked ok, it came off when I was skinning in really wet snow and my skins stretched out, but for the most part it was set and forget and I wasn't unhappy with it. When I first moved to SoCal four years ago the skin stretching was an issue for the first time and I bought this kit intending to fix it, but it wasn't enough of a problem to make me think about it when I wasn't skinning so I didn't get around to it.
The reason I finally installed it is that I bought a tele setup and my new skis are 4cm longer than my AT skis. The width is pretty similar throughout so I didn't want to buy new skins, so I installed this so I could swap skins between skis, and it works just great for that.
Installation isn't trivial, but it's not a huge pain. Cutting the notch in the back of the skins for these wasn't too difficult, make sure you have a sharp blade (I still find my ClimbingSkinsDirect cutter works great). Also, making the holes for the rivets was tricky. I found making a hole with a nail, then screwing a drywall screw through the hole and pulling it straight out with plyers worked quite well.
Noted the reviews recommending very sharp knife. No, just take an old dull knife and heat it with your propane torch, or on a kitchen range. Same old trick for making the rivet holes: hold a nail in a Vice Grip or any locking pliers, and heat it.
Reason I have started to replace Clipfix with STS is that STS allows for skin stretch, where as Clipfix requires perfect skin length adjustment (and re-adjustments). Clipfix does clip on more easily; skied with these today.
I used this Black Diamond STS kit and the G3 connector kit to make a functional tail clip for splitboard skins.
A warning to all: this kit does NOT come with the tip attachments like the picture would suggest (thus the 1-star rating). LAME.
This pic shows all that comes with this kit.
