90° Angle Brackets

Available in Metric and English Standard versions, these adapter plates enable the mounting of rotary or translation stages, optic mounts and other positioning equipment at 90° to the breadboard, bench plate or lab table work surface. Brackets accommodate either ¼ or M6 mounting connections, depending on model selected. Common bracket types have only slots (no threaded holes) for both English and Metric platform integration. Small size has three 2" long slots on both faces. Large size has five 2" long slots on base and ten 1-½" long slots on larger mounting face (5 rows with 1" gap at center).
