Quality
This is a great bar. I used it for my bigger wires to run to my amps and organize my wires in the engine bay. It was easy to install and the big screws make for a good connection. It looks good. Fits good, and will last a long time. It is solid. It is a good value for my money

Solid Power Block — Easy Install & Works Great
This fused power distribution block was exactly what I needed for my car audio setup. It’s sturdy, easy to install, and keeps my wiring clean and organized. The fuses fit tight, the cover snaps on well, and everything feels secure. Perfect for amps or accessory add-ons. Great quality for the price!

Good fuse block, connections are good. Encapsulate case and cover works as designed. A bit delicate and for somebody that is Tammy or impatient it might break.
