    Wow. Glass fiber reinforced housing, well polished stainless hardware, good quality goo. Worth the money.

    This was great for cleaning up the battery bay of the RV. Since Ive added the two LiFePO 4 batteries in parallel, there were 4 or 5 cables attached to the positive of one battery, so with this bus bar, I was able to get that down to 2. They included a little tube of NoOx and that was a great bonus. Used a couple of self tapping screws to mount it to the frame rail, got everything snugged down and applied a light coating of the grease to all exposed connectors. Really appreciate the included cover too. Much less likely Ill be shorting out these high current connections.

    Larger than expected but seems like good quality.

    Wow these things are very well built, I used these to split some power on my truck to connect a DC/AC inverter and its just what I needed. Quality of the hardware is nice as well, so many times I have bought something and the item itself is great but the hardware the manufacturer puts in the box has to be replaced with better quality, not this.

    These busbar/distribution-blocks are good-quality, well-made units that suited my application perfectly. They are being used on my boat so the stainless steel metal parts are well suited to the damp environment, and the covers protect from accidental contact.

    If youre one of those people who have like 10 wires stuffed under one screw for the accessories running in your car then think about running 1 heavy duty cable to one of these bus bars then youll have a nice neat place to get your 12 volt battery power from. This is designed for the positive side or hot side and is isolated from its mounting. What I like about this product is that it has a cover so that you are less likely to touch a terminal and short out or ground unintentionally. This will be good to run some high-draw accessories but not like an automotive starter motor or something directly. Just know this is positive (or negative) only and you will need another for negative side.

    I wanted to clean up my engine compartment and Get rid of some wires running to my positive post on my battery. I bought this bus bar and mounted it on the inner fender. It looks nice and was easy to install all the connections. The terminal cover is nice to help avoid accidental shorts.
