Customer Reviews for VEVOR Drawer Slides with Lock, 1 Pair 56 inch, Heavy-Duty Industrial Steel up to 500 lbs Capacity, 3-Fold Full Extension, Ball Bearing Lock-in & Lock-Out, Side Mount
Just what I wanted. Very heavy duty, ball bearings. Careful, it might be more than you want. I needed something that would carry over 200 lbs when fully extended to 52 inches. These fit that requirement.
I built a shelf for my sandblasting cabinet and wanted it to slide in and out. Welded this to the bracket I made for the cabinet and used lag screws to hold it down to the shelf. Slides great! I have no hesitations about it holding the weight.
As advertised. Hardware store bolts will fit the holes.
Don't recall the size of the bolts I used but I was concerned about getting some special hardware to hold my generator on these rails. Just bring them to a hardware store with you and you can find bolts that will fit the holes. My 100 lb generator now slides out on rails on my motorhome. Happy with this hardware.
I was worried about how to install these. I had a limited knowledge on drawer slides and found these to be strong and easy to install.I will certainly buy this brand again.
