- 5 of 5 Drawer Slides September 4th, 2026
by Gayle from STURBRIDGE, MAMy contractor was just here installing the drawer slides. Took him a bit to determine how they should be attached and how to fit into my face-framed cabinet. Currently installed and working nice and smooth. I appreciate the help from Frank at Cabinet Parts.com with helping me find the appropriate slider for my drawer and explaining the install process.

I had to return the part due to it being the wrong size. I will reorder a new part
- 4 of 5 | September 8th, 2026
Would have given a five star except screws that are sold along with drawer slides are shipped from a different location, presumably by a third party retailer. Tracking says shipped by USPostal Service which is slow and unreliable lately. Been 2 weeks and
