The name speaks for itself. I have used this brand of fence on all my table saws for the past 20 years plus! At one time I had 7 in operation at one time. Precision is outstanding with no movement or loosening of the adustments even under heavy day to day use. This past purchase of the 30 inch unit was for my shop use (home). I am retired now and have never forgot the reliability, quality and performance of the Delta fence systems.
