I am about ready to build all new kitchen cabinets for my home....and I had planned to use drawer slides from Rockler...either Accuride or CenterLines...with either a soft close or self close features. The price is not scaring me away from these....it's the reviews on some of them that is giving me pause. From what I understand, there is very little tolerance when it comes to the width of the drawer and the opening of the face frames on the cabinets. Apparently you need a half inch on each side and from what I read...any deviation from the half inch means binding and rough operation of the drawers. I am sure that some of you must have gone through the installation of these particular slides in the past and I am asking for your views on the installation and how difficult/easy it was and if there was much tolerance in the widths of the drawers as opposed to the face frame openings for the drawers. My wife would be perfectly happy with the cheaper and quite honestly, much easier slides that use the rollers on each side of the face frame and the single down the middle of the opening front to back track that guides the single nylon wheel mounted to the back of the drawer carcass. But I wanted to give her a dream kitchen with the fancy closing drawers and if at all possible, that is what I would like to do...but these review horror stories are causing me to rethink my plans. Any thoughts?
