Lots of space for wire installation across the board. The nuts all have an integrated locking washer which makes for a really secure connections to the bus bar. Great product and would purchase again if necessary.

### ⭐⭐⭐⭐⭐ Review
*by T***G on 21 August 2018*

This is not what I was looking for when I found it, but it does the job perfectly. I have "trays" of HR1221W SLA batteries from a defunct UPS that I just couldn't leave alone, and needed an inexpensive way to turn 8 12v batteries wired in series (for 96v total) into 8 12v batteries wired in parallel (for 12v total) so I could power some more common DC loads. This bus bar does the job, leaving me two pair of terminals to hook up a pair of loads. It's not what I was envisioning, but works perfectly. Construction of the part is solid (as are most things from Blue Sea) and while the price seems high for such a simple product it's inline with other similar options... maybe even cheap. Each of the 20 terminals is a #8 screw, so #8 spade or ring terminals work perfectly.
