High Quality High Amperage Bus Bars
Really good quality with a real high Amp rating for the whole bus bar, unlike cheaper ones that divide the rating between the terminals. This is very much so worth the money. You can tell immediately by the weight that they are of superior quality. Up for the job needed.

Top quality - worth the extra money
These aren't the cheapest busbars, but when you are dealing with 300Amps, you don't want to cut too many corners. Plenty of room to get 3 or 4 crimped cables on to each of the 4 bolts. The housing is reassuringly thich and sturdy, with slotted blanks to allow cables from all directions

Watch the screws!
This is a great bit of kit but... When mounted on the wall just be careful when taking out the screws. There is nothing stopping them coming right out and dropping down to the depths never to be found again... Like I did! The bolts are M10 which are a bit big, M8 would have been easier as I had to change a lot of lugs to for this to work. Overall it does the job well but it really is majorly overpriced for what it is.

Well made, will do nicely
This has 8 x 2.5mm thin wall cables bolted to it, I’ve just realised on is out of order, oops, I’ll sort that out! A2 stainless steel studs and nuts, I’m not sure what the big bar they bolt on to is, but, it is big and will handle a good current.

Impressed
Very pleased with this heavy weight bus bar . I bought as the single four positive and negative were out of stock. Pleased as I'm going to cut in half to give me two separated bus bars, and gives me higher amp carrying too.

Bra stabilt produkt. Bara att den inte finns med fler kontakte i lådan är lite hemsk.

Perfetto per nodi elettrici importanti: questo l'ho usato come barra di connessione fra una batteria Lifepo4 24V e un inverter ibrido (con potenza nominale massima di 4.2kW) e mi ha permesso di fare un'installazione molto pulita
