Hourglass

The Hourglass style clip uses 3 screws to attach to the scales and tapers towards the middle before flaring out at the end, resulting in an "hourglass" silhouette. These come in a variety of finishes: chrome, black and dark chrome. They also come with and without a pivot hole cutout in them.
