Bought five pairs of these slides for a dresser I was building. The slides themselves are very good and KJP has them for a good price. Unfortunately, the description has several errors:
- They do not have elongated holes for depth adjustment
- They do not have a rear side-to-side adjustment (there is a tilt adjustment in the rear, not side-to-side)
- They do not have four-dimensional adjustments (you can adjust each side up and down, so two dimensions)
Blum makes many different models of slides with slight variations, so I'm guessing the description may have been taken from a different model. The slides themselves are good as long as you're aware of the limitations.
