These are slicker than fryer grease on a linolium floor. Best form and function of any keck I've ever used and they fit on those wierd joints nothing else fit.
Loved them! WIsh I knew you had cool tools as well!
Great sense of security using these clips. Plastic-on-glass can be an eyesore imho so I'm very happy with this alternative. I only wish it were back in stock and compatible with my RBR piece
