Very neat system for mounting fuse directly to battery terminal. Changed battery lugs to cargo type so that fuse block would be mounted vertically.

Well made, easy to fit

Très compact, plus sécuritaire que les fusibles "inline" ou de type ANL , vous ne vous trompez pas côté qualité... n'oubliez pas de commander aussi les fusibles, elles ne sont pas incluses ...

I bought 2 of these and as I thought, they are very well made and I'm sure will work for me very well.
