Review: Time will tell, but looks very good - Have not installed this, but very impressed with the build. Very sturdey and also appreciate the cover.
Review: Worked great for my application - I needed this for my RV and it worked out great! I had several negative terminals that were sharing a single screw attached to the frame. I needed to add negative wire for a solar charge controller and this bus bar worked great. I did discover after the initial installation that I needed to ground the bus bar to the frame. But everything works and looks good now.

Well made product. Sturdy and easily to install. I used this in a restoration of a 1948 Dodge pick-up restoration to provide easy distribution of power in conversion to 12 V negative ground from 6 volt positive ground.
