Each of the 20 terminals is a #8 screw
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.

Good Quality Bus Bar
Used this in my boat to make wiring cleaner and easier and it worked great. Easy to work with and easy to install and still working after many years. 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.

Good quality.
Works great. Used this to combine 3 100watt solar panels in parallel. Have room left over when I add more panels.

The Perfect Solution
The Blue Sea Systems 2702 Dual Busbar enabled me to sort out the wiring of 12-volt accessories under the console of my boat. It was easy to mount and the quality hardware allows tightening of all connections without fear of stripping threads. A must-have to complete a proper installation. (And, it made it look like I know what I'm doing!)
