These units are very nice..heavy well built..I like them so well I’m going to order the same product but with larger lugs..

Does the job.
This works well. Cleans up the install on my 36 volt lithium battery conversion on my EZGO golf cart.

perfect for my situation
Got these to move all the wired devices onto separate contacts for the solar setup in my van. I had at least five devices all going to the single end terminals on my leisure batteries and it was quite a stack! This is much nicer, safer, and makes it easier to remove/repair just a single item if I ever need to. I won't have to remove the entire stack and unplug my panels just to address one issue. One of the best buys I made recently for my vanlife project.

Works great, seems strong
Used this while relocating a travel trailer battery (LiFePO4, you don't want to bring lead-acid batteries inside!). Looks good, seems quite rugged, came with good quality crimp terminals.

Basic bus bar
The bus bars themselves are 3mm x 21mm x 130mm. The 8mm studs are spaced about 21 mm apart. The studs appear to be bolts which are screwed into the bar bar from below and are set into the plastic base. Since the bolts are threaded into the bus bar, I believe you can get adequate torque to secure large ring terminals. The locking nuts are serrated flange nuts. While sufficient, I prefer a regular nut, locking washer and flat washer combination. Six open ended ring terminals for 2 AWG (35 mm^2) wire along with 6 pieces of heat shrink tubing are included. Each bus bar has a clear cover which is secured with two plastic nuts. The covers provide a modest amount of protection against accidental shorts. All in all, I like these basic bus bars. I think they are a good budget option. I am going to use them, but not for the claimed amperage.

Couldn't be happier
Solid bus with 1/4" thick plated copper bar and heavy lugs. Much better then the screw-down bus I had prior. I knew it was going to be solid when I first grabbed the package - heavier then expected.
