I bought some Blum drawers glides the other week. They are the under
mount type. I picked them because they don't obstruct the dovetails
but they can be a bit tricky to install, the thickness of the material
used for the drawers de terming the size of the drawers. Are there
other quality glides out there that will give me the same benefits
that are a little easier to install?
