I stumbled on a real nice tool it is called lock n lube it is a replacement hose end for your grease gun. I have a backhoe with I guess thirty grease points , this tool makes greasing so much easier , there is no fighting to get the correct angle on the zerk it locks on. will it get to every fitting ,no if they are close quarters.
