I lost this overhead test tip on my job site network tester in a different condition and will never get it back! It's really nice that I can just order another one online for less than what Home Depot would sell it to me for. With Revain Prime I got it to my hotel room in 2 days (no less than a Sunday) which was fantastic. Eliminated downtime from not having the right tools on site. This is a direct replacement from Klein. Exactly the same as the end cap that came with the original unit.
