Excellent job by production being able to use grips for the anodizing bath instead of a hole in the center of the part.

Always quick and easy dealing with Tammy – great communication! We look forward to doing business with RapidDirect soon.

The 4 parts look great and work very well. This order was to solve a problem on some equipment, so only the 4 parts were needed.

We were very pleased with your quality, cost and delivery, and will certainly order from you in the future. I have also recommended you to friends who own other companies.
