Klein makes a knect pass through SAE socket set that comes with a pass through ratchet and a hollow extension adapter where you can either attach it to the ratcheting impact 11 in 1, or put it into an impact
My main set up for a lot of jobs is the Knipex forged wire strippers, 250mm auto adjust cobras, the klein ratcheting impact 11 in 1, and the milwaukee fastback 6 in 1. I use other tools obviously, but these are the usual suspects.
Did you see the ratchet version of this tool? I was at lowe's and I ignore it thinking it was this one. Then it pop up on my feed that it was a ratchet version. And I saw it can pair with the klein knect you have.
Okay I found 2 in store that have the G at the end. It's the exact same screwdriver. What it looks like is Lowes' exclusive part number (Home Depot was R hence the 32500HDR part number). The packaging graphics are a little different. The new 7 in 1 socket set that you can only find at Lowes right now has a G at the end too.
