I have not. Didn’t realize they existed- I guess I did not look hard enough. Thanks.
Good call.Based on the Armstrong, Matco & S-K mix of random lengths & drive sizes I have they are all by the same OE. Pretty good chance AJ makes them.
They do work rather nicely IMO.
I wonder if AJ made Armstrong's too, or if they picked up the ball and ran with it after Armstrong shuttered.The locking extensions,AJ Manufacturing make them for Mac,Matco and Snap On.Differences are what is put on the ratchet side and part numbers


I am not sure.I know it was mentioned in one of Flat Rate Master's youtube videosI wonder if AJ made Armstrong's too, or if they picked up the ball and ran with it after Armstrong shuttered.
I know Cripe distributing offered several of the Armstrong versions but, that stock may have dried up by now. I really like my MAC versions as they have knurling around the female square drive end.![]()
