Depends…me personally, I don’t like slipin’ off a nipple till I am done with it. So I would echo what @RCW said. I would offer look at the combo pack of fittings…there are several that can be helpful depending on what zerks you need to reach.
just an fyi
my Lock N lube just crapped out Would not lock onto a zerk at all.
I replace it with this: zerk adapter
Right off the bat I like the way you grip this vs the Lock N Lube. Tomorrow is the test - I need to grease the FEL
will let you know how it goes.
