Nice heavy duty adapters, however.. being offset was the reason I got these, I had to modify them by using a sander and grinding flat spots in the correct location of nipple going into amp as the factory flat spots were in wrong location

I ordered this for my husband’s sound system and he used it on various connectors. Very clean work, easy, and simple to use. Highly recommend this product!

Used it to adapt my 1/0 gauge wires to my subwoofer amp which takes 4 gauge wires. Fit perfectly and was easy to install.

I had to grind them down to fit my Amp and the material is malleable enough to do so and it worked out great good quality.

Ordered these thinking it would work for my application. The neck was just to long and there was no included heat shrink for the adapters. You can notice in the picture the difference in height vs the reducers that I used. Might be good to use for ground wires, but not for a positive wire. The adapter in this listing is the adapter on the left in the picture.
