If you have ever installed 4-post rack shelves, you have probably dropped a screw or two or pinched your fingers more than you want to admit. Black Box has come to the rescue with their tool-less shelves.
The flanges on the telescoping mounting ears fit simply into the cage nut rack rails with no problem. To help you with lost screws and bruised fingers, we are offering these rack shelves at a special price. Pricing will be for a very limited time, so if you are interested, I would check them out now. On the other hand, these are so easy to use, they are worth it at most any price!
