Manufacturer: OSP. This is NOT a sliding keyboard tray for under-desk mount. | This sliding shelf is for use in professional AVL 19" racks. This unit must be mounted using both front and rear rack rails to avoid bending.
It works just like it should. It took a minute but I was able to install it in my rack. I use it to hold a recorder or drum machine and it does that nicely. It is solidly built so I expect it to last. It slides out fairly smoothly.
Smooth action, comes far out from cabinet. I used this in my entertainment center so I could pull out my turntable far enough to lift lid and set record album. However, had to fabricate two 1"x2"x15" wood strips and mount on side of cabinet so I could screw down sliding mount. Worked out well.
