This oversize shelf edge strip functions dually as a label/sign holder and product stop because of its mounting height.  The generous size was a pleasant experience which could have been capitalized on better if labels were not identical for each facing.  A slide-in profile facilitated set up. But a thumb-screw C-clamp mounted to glass shelves (with or without swivel on the end of the threaded shaft) is not advisable. Safety aside I actually liked the spaciousness and look.  Forgiving extruded label holder profiles that mount safely directly to glass (and solid) shelves can be had from any full-service manufacturer. A range of sizes and colors including clear to match the shelf are available to suit any need.
