The drawers the slides were fitted to were finicky. As an old chest of drawers is, uneven wear resulted in mis-alignment and abuse tearing of the wood. A light sanding of the wood bars, slight expansion of the metal slide, corrected alignment measurement, resulted in smooth non binding drawer sliding.
They work just fine. Very satisfied with the results.
Fit perfectly.
It works, but it's a bit tight around the drawer component.
Would love to write a review. Order confirmation on 4/10 and item still not received on 4/26.
