The standard 1/4 works out of the box. I was told I should cut the old terminal and use new sleeves and nuts to avoid potential leakage so I found this set. I only need one but as an amateur, this set gives me more chance of messing things up and just cut and use a new set. It is definitely much cheaper (per set) compared to just buying exact number of nuts/sleeves. Review: Good quality - Excellent assortment of items and well built . Easy assembly.
