This item works with small handle residential gates and for commercial gates.
I found this listing by googling zak gate pass tool and in the description from the google said that this is the 2 piece set .however there us not much of a description once you are at this site but from google the description states that its a 2 piece set so i was dissapointed to find that this IS NOT the 2 piece gate pass set
As with everything in life it is best to rely on information directly from the source rather than other people or websites. It would appear that the description you saw on another website is extremely outdated. Zak Tool stopped offering this item in a 2-peice set a very long time ago (approaching a year now). The reason being is they found a small and large tool made no difference--they both worked the same to open the same type of gates. So it's now only offered as a one piece item--everywhere. Our description, title, part # and picture all showed this was a 1 piece item when you ordered.
