FRMSAET Heavy Duty 12/14/16/18 inches Thickness Steel Construction Ball Bearing Keyboard Slides Keyboard Drawer Slides Tray Accessories Cabinet Furniture Hardware Rails (14 inches, Black)

I purchased a board 3/4" x 14" x 36" from Lowes. I ised these frames and the board to make a keyboard shelf for my desk. And I had already built my desk with 3/4" for the top. I did not use the included screws to attach it to the wood as other reviews said they were low quality. I did use the included machine screws to put the frames together and those were easy to strip. Overall pretty simple process, just had to make sure the screws I purchased where short enough to not go through my wood, but long enough to be sturdy. The shelf is stable enough, but it does wobble slightly when locking it fully out or fully in. The locking is pretty strong and requires some force to pull it back out.

I purchased these because the rails that came with my desk literally pulled apart and the bearings fell all over the floor, they were cheap generics. I had to modify the desk as the original mounting hardware was welded in but these had the most options when it came to installing. You can adjust the height, the direction the mounting flanges attach to the rails and it enabled me to remove the old hardware and install these in place and reuse everything else from the desk. Including the metal and glass keyboard tray. item is exactly as shown in the amazon description. Came with screws that I was able to use even with the metal desk. I am super happy with my purchase. I can finally rest my hands on my wrist rest without fear of it breaking off the desk. I bought 16 inch size which turned out perfect, they are exactly 16 inches long, they have 10 inches of travel.The only downside has nothing to do with the slides and more of a desk complaint. There was limited space where I could attach the mounting hardware to the desk and you cannot relocate the mounts on the rails as those points are fixed so the tray slides a couple inches past the front edge of the desk which in turn does limit how far out the tray can slide out. It is a mix of desk limitations with the inability to move the mounting points along the rail. Other than that I have no other complaints.Overall if I needed to add a tray to another desk I would definitely buy these again and recommend these to anyone reading this.

I used a 3/4 inch piece of pine board to make a keyboard tray with these rollers. It rolls fairly smoothly, and it will lock in the extended position so that it wont move while you type/work. Despite being firmly affixed to my desk, the connecting brackets allow for enough flex that you must close the tray with both hands on either side when it is fully extended in the “locked” position. Otherwise, it will flex and seize up temporarily. Once you get used to it, it works well, and I see no reason it shouldn’t last a long time.

The media could not be loaded. These are pretty decent slides and worked great for my new router cabinet project.I inverted them and mounted to the bottom shelf, then made a organizer shelf for router bits.The slides are smooth and quiet and I am very happy with them.

The screws used to attach the shelf are fine because it sits on the brackets, but the screws used to attach the entire assembly are inadequate. No big deal for anyone with a well stocked junk drawer.

Heavy Duty Keyboard Ball Bearing Keyboard Slides: $35.99 at the time of reviewWhen I ordered my Autonomous desk three years ago, the only thing I found lacking in it was the absence of a keyboard tray. So I took on the task of making my own. It took a large bamboo cutting board and used a set of keyboard slides. Eventually I decided to get a bigger tray which necessitated new, heavier duty slides. I chose these ones from Frmsaet.*What I liked*:These sliders (like my older ones) are adjustable height. This is nice if you have a tight space or need a deeper tray.They do come with a full set of screws. This is good for most people but due to the shallow depth of the boards in my desk, I needed to use shorter screws.*What I didn't like*:Unfortunately, these just aren’t that heavy duty. The previous slides I had were a little thicker metal and felt more sturdy (sadly, the catch that kept the keyboard in wore out so I needed to replace them). These sliders wobble back and forth a little when I push my tray in which results in a slight grind, making it harder to push in all the way.*The Bottom Line:*The bottom line here is that I’ve already installed these and it was a pain (through no fault of theirs). So I won’t be removing them until/unless they break or wear out. But they aren’t as good as my old set and I definitely wouldn’t call them heavy duty. Three stars out five because they technically work, just not as well as they could. I wouldn’t buy these over again.

Used this to mount a drawer on my 1922 made roll top desk that I converted to a standing desk. These worked perfectly to mount the center drawer for continued use.

El producto es bueno. Lo elegí en gran parte por el tiempo de entrega, pero no lo cumplieron. Debido a eso, pude empezar a usar el producto 10 días después.

Works great. Very solid and high quality. I used a heavier piece of wood from the side of my desk shelves which is quite wide, but it holds up very well. Just turned my desk into a much more expensive one with very little money. It does take some time to mount it though so measure carefully and make sure you have the right tools! i.e., tape measure, drill, pencil, lots of patience.Also, much cheaper than what they sell at the big box stores.

Es fuerte y muy funcional, muy contento con la compra

It doesn't have any load bearing support for keyoard tray for extra production, also corners are not as mentions in the product description. Worst quality. I got just simple sliders. Its not value for money. Size, weight are good & Smooth.

It is easy to assemble but once you do it wobbles to left and right a tad and despite the fact that I tried to align it perfectly, it still doesnt have a smooth open and close movement. All of these might be because I have a 150cm tray in between for my digital piano and it weighs 12kg which is still in the boundaries of what is stated in the product details. It doesnt feel durable but it hasnt failed on me. Everynight I go to sleep fearing that it might fall but no its alright.
