Commercial grade plates
Plates are just as hoped. The look/feel/build feel of very high quality. The plates spin 360 deg. move freely side to side, and front to back once lock plates are removed from the bottom. The degree gauge with pointer is an awesome feature. It allows for caster to be measured accurately when using a bubble gauge. I bought these plates for personal use, but from what I have used, and seen in a shop they should work perfect on an alignment rack. Also, Steve offered great customer service, and made the entire purchase a pleasure.
