## Questions & Answers

**Q: could I fit 3 sets of these 2u extender brackets into a 6u rack, or would they bump into each other?**
A: Never tried it but I do not see why not. Also you can certainly get 4u extenders and have you checked for a 6u extender. Also look at your rack to see it you can simply move the main bars forward, most are adjustable, as you want to extend all 6us of you 6u rack.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Well made clever little offsets.
*by D***R on 20 July 2025*

Handy 19" rack accessory.

### ⭐⭐⭐⭐⭐ Universal square-hole rack depth adapter
*by S***V on 6 August 2019*

Perfect for use with my StarTech 42U four post rack. I made the rack very deep (900mm) when I constructed it, which was fine for all but two devices (both from Dell). Using this adapter meant my Dell sliding rail would fit properly in the rack.This adapter kit is suitable for almost any 2U device and square-hole rack, and works to either increase or reduce the rack depth. If this is what you're looking for, this is the right adapter for the job.

### ⭐⭐⭐⭐ Worth the money
*by M***. on 26 May 2023*

Fitted my rack perfectly and does the job, if your rack mounted unit is heavy you might get a little twisting though
