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

Works great. Install was not too bad. I had a 2nd person help. Not sure how you do it w/just one person. I had someone hold the shelf assembly in place while I drilled a small pilot hole for each screw. Then once it's held in place, put the rest of the screws in. Shelf is a little wobbly going in and out, but not a problem for holding a keyboard. Very sturdy once the shelf is completely pulled out.

Super durable, quiet. No friction problems. Simple instructions and tools. Holds my Keystation 49 and Mouse, I'm a bit heavy handed, so I'd say these can bear a lot of weight. I suggest installing with screw anchors for additional security.

Sturdy, good quality product. Slides *very* smoothly. Brief (but adequate) installation instructions included. Plenty of extra screws included. However, installing is pretty hard to do unless you can flip the desk surface upside down (easy with a new, portable, desk - nearly impossible when replacing a broken keyboard drawer). After many attempts, I ended up screwing one bracket to the underside of the desk, then attaching the keyboard tray (with 3 brackets already attached) to that bracket, and even then I needed an extra set of hands (that's what teenage children are for) to hold it steady so that I could screw in a 2nd bracket to the desk. 3rd/4th brackets were no problem.

Using the 12" rails with a 10" x 36" white shelf from Home Depot (which cost about $11). The hardware feels sturdy. It's just slightly wobbly while pulling in and out, but otherwise stable especially when actually using it which is the most important. Love that I can adjust the height higher/lower in the future if needed. Installation was straightforward with no surprises, and all needed screws were provided. Happy with my purchase and expecting to get years of use out of this.

Used it under my computer desk to build a slide out for my midi keyboard , it completely changed my life.

Heavy Duty Keyboard Ball Bearing Keyboard Slides: $35.99 at the time of review When 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.

These 12" tray glides are well built and install easily if you are the least bit handy. One warning: Although they are 12" glides, they slide out only 8". This is indicated in the diagrams in the ad. I had to make some last minute changes in my design, but it all worked out well. Although it is designed for keyboard trays I repurposed it as a slide-out extension for my desk. I used a 1/2" thick x 10" deep x12" wide cutting board and used 1/4" spacers to make it even with the top edge the slides.

Just as advertised. Super strong, seemly well made. I am making a shallow desk drawer next week for a desk I built and look forward to using these brackets to make it happen.

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.

Nous avons acheté ces glissières pour installer une tablette sur mesure en mélamine. L’installation en soi est très facile. Nous avons eu un peu de difficulté pour visser, mais c’était uniquement dû à la configuration de notre bureau, qui laissait peu d’espace de chaque côté pour accéder aux vis. Plusieurs vis de tailles différentes sont incluses, ce qui permet de bien s’adapter à la configuration du bureau. La hauteur et la distance par rapport au dessus du bureau sont ajustables, ce qui nous a permis d’installer la tablette exactement à la bonne hauteur pour un usage ergonomique. Une fois installée, la tablette est solidement fixée. Elle coulisse bien, le roulement à billes fonctionne efficacement et elle reste bien en place à l’usage, sans tendance à reculer. Nous sommes très satisfaits : ce sont de bons rails, solides et fiables.

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.

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.

Great quality. Pretty straight forward installation. Sturdy and stays in place.
