Clamp removal and installation tips:
To remove the clamps - on the side opposite the crimp on the clamp you will see a seam or tab on the clamp - with a thin screwdriver pry up on that seam and the clamp will come apart, be careful when prying so as to not stab yourself or fling a bit of clamp into your eye. Once the clamp comes apart you can unwind the clamp.
To crimp you can use a pair of dykes to squeeze the clamps together, or tile snips.
