These zinc alloy shelf supports have two silicone-padded jaws to securely grip glass or acrylic shelves. The lower jaw is mounted on the cabinet wall and the upper jaw slots into it, adjusting to fit 4mm to 8mm shelves. A plastic clip locks the jaw setting.
Sold in packages of four, with either an included pin sized to fit 5mm holes or a countersunk hole for mounting with a screw (not included; flathead #6 screw recommended).
They adjust to fit glass or acrylic shelves from 4mm to 8mm thick, with the upper jaw sliding into position and locking with a plastic clip.
No, both jaws are padded with silicone where they contact the shelf, so there's no direct metal-to-glass contact that could chip the edge.
Choose the 5mm pin version if your cabinet already has standard shelf-pin holes drilled, or the screw-hole version if you'd rather anchor the support with a #6 flathead screw into solid material.
Each package includes four supports, typically enough for one glass shelf, with two supports mounted at each end.
The jaws and body are made from zinc alloy for rigidity, with silicone padding where they contact the glass or acrylic shelf.
