I've always appreciated the clean lines given by the type of drawer pull which extends all the way across the top or bottom edge of a drawer. Although there's many different molding profiles available, in both metal and wood, which provide that feature, the all share one drawback when used on overlay drawers: unfinished ends. In typical cabinet production, the molding is purchased in stock lengths and cut to required size. This leaves rough ends which require additional finishing of some sort, like rounding and sanding, to make the ends safe to the touch; that's especially true for metal extrusions. Nothing I'd ever seen solved this.
Then a project I was designing, which required thirty-five identical 2-drawer file drawer pedestals, inspired this drawer pull system, consisting of an extrusion with fitted end caps. I really wanted that clean-line look, but since this didn't yet exist, and nothing else fit, we ultimately used a standard arched wire pull. However, I took a sidebar and designed the GripRail, drew and rendered the concept, and pitched the idea to Doug Mockett, who had just gotten their first 3D printer. They printed from my files and sent me the prototypes. The next week I got a 3D printer and now we both prototyped and refined the design, and it was accepted for production.
The caps cover and finish the rough-cut ends, with no labor required. This extrusion shape also addresses another shortcoming of current designs, which must be grasped from underneath, and are somewhat unfriendly for long fingernails. GripRail is grasped with a pinching grip between thumb and forefinger, so it's fingernail-friendly, and easy to grab. It's sleek and trim when applied, and provides a matching or contrast detail element in the end caps. DP215
