52-010-005-0 Caliper Accessory Kit for 4-12 Calipers

No issue installing these onto my 4/6/8/12” Mitutoyo absolute digimatic calipers. I also have a Fowler caliper that it fits on. Not sure why other people have issues with fitment as it seems that it will fit a wide range of calipers.My only complaint would be that I would like to have a couple shorter screw in probes but every part including the piece that attaches to the caliper is precision ground and can be used for referencing as well. This works well for getting down deeper into holes or getting around a feature to measure something else.

Helped to expand our calipers for some specific testing and measurements.

Had to glue ours on.

Description on store page is incorrect. Read it and you'll see what I mean.

I ordered this with a new Fowler caliper. They do not fit the jaws of the calipers. I'm not sure why they are so tight I will need to file down the edges to make it work.

Not the best for the price

First rail was tapped, second rail wasn't tapped.
