A minimalist design will ensure less visual clutter. Knobs and long pulls are nice, but they aren't necessary.
Luxul's aluminium strip handles for frameless back painted & mirror doors have an inwardly beveled edge for your fingers to wrap around on one side, allowing you to pull the door open toward you. The space created by this design will appear as a clean, recessed gap between each cabinet or drawer.
The C strip handle is designed for the botttom edge of overhead doors. Unobtrusive, yet so practical - especially for mirror doors. Available in Clear Anodised Aluminium.
