DaierTek Power Distribution Block 300A 12V Bus Bar 5/16" 6 Post Terminal Block with Cover Max 48V DC/300V AC for Marine Automotive Car Truck Solar Systems (Positive and Ground)

I haven't used these yet but they do seem like they're good quality.

No issues to speak of. I used to aggregate my two(2) LifePo4 batteries together in my toy hauler using 2/0 AWG wire. So far, so good!

The studs can come loose on the ends. Make sure you flip it over and tighten with Allen wrench before installing and locking in wires on studs. Well built overall.

Works like it said, happy with this

Each end stud can easily be removed. I was able to remove one of the end bolts on the red buss and bolt it directly to a circuit breaker instead of cutting and crimping a short cable to bridge the two. Very handy.

After I built my brackets and put my auxiliary battery in my truck it works fine but the red one the tray if you call it is a little loose and I can't figure out how to tighten it I tried to take all the bolts out but I can't seem to get it apart to tighten it

Bus bars for negative and positive power associated with solar setup.

This is a solid block, it's got enough heft to it I can trust it's not made of inferior materials. The cover doesn't feel like an afterthought and I like that it stays put without having to use screws. The value is good for the price paid. I wouldn't hesitate to buy another if I needed it.

I am disapointed severly in this product. i ordered them based on the images. product arrrived late. the Bus Bars are GLUED to the based, and mine was glued on crooked. the finish on the busbars is crude and not premium in any way. also the red on the positive bus bar looks like it sat in the sun for 4 years its not what i would even consider red. they are more pink at this point . over all this product is not worth the money. very disapointed.
