The 360 Series Angle Brackets are rigid, angled mounting plates with slotted faces. The 30, 45 and 90 degree angles are accurate to within ±2 arc min. Model 360-90 is useful for building 3-axis linear stage assemblies and as a platform with rod mounted components. Brackets may be combined to provide stable compound angle supports. Pairs of 360-30 or 360-45 brackets bolted together on hypotenuse faces provide coarse-adjustable height platforms of exceptional rigidity.
