Finish is anodized black aluminum and includes a heat treated cad plated steel bolt for mounting the guard to the stand.
The 1.75" stand is generally used with the short 4in. snout and the 3.00" stand with a 5in. snout.
Stands are sold individually and most all roots blower belt guards use four stands per set up. Longer snouts should use a blower snout clamp to mount the blower belt guard.
