Review on Gobrico 18-Inch Full Extension Heavy Duty Soft Close Rear/Side Mount Ball Bearing Drawer Slides With Brackets, 10Pairs by Dave Tapia

I'm speechless at the moment. Many review did claim these rails are not as smooth as other products. I took a chance to order with the review raving about excellent built quality. Standard ball bearing rails usually requires only 1/2" for each side which I have. These rails were so tight that they were scrap against the side of my 1st draw. Have been trying to get in contact with seller but never respond back to assist my installation. Instructions came with are useless. Really wanted to return but they are heavy and didn't want to waste more time. If you end up getting these rails, relubed those ball bearing. Very terrible when i looking at those ball bearing barely lube.
