Gardner BenderGSPA-4/0 6-0000 AWG Aluminum Splicer Reducer

I chose this specific one because it has rounded edges and that is what I needed for my use but the product that I got was just a square like all the other ones I have seen.

Worked great for splicing my 4/0 dc forklift 36V battery lead!

Easy to use but it to heavy

Great product arrived as described

Worked well in a pinch.

Used to extend several 2/0 Aluminum cables along with shrink tubes.
