Climax Metal 2C-125 Steel Two-Piece Clamping Collar, Black Oxide Plating, 1-1/4" Bore Size, 2-1/16" OD, With 1/4-28 x 3/4 Set Screw, 1 Count

Its exactly as described. I was hoping it was bigger, but that was my bad. solid steel

The wheel itself was my issue but this is preventive maintenance.

I wouldn’t use this for what it’s advertised for , extremely painful and pinches out of this world . Heed the warning .. do not put on your junk .

I used this to make a depth stop for a vintage drill press. I'm not sure what some other reviewers were using them for.Well made and not zinc-plated, which was nice for welding without poisoning myself or spending time removing the plating. The cap screws that tighten are ASE (3/16") hex wrench, which is nice as it matches my drill press--fewer tools. It welds and tools well. It's concentric and fits the advertised size perfectly.No complaints!

It seemed as described. It just didn’t work for me so I returned it. I think maybe the measurements I had were wrong but didn’t realize at the time. If it ever comes with a 1.5” bore at a good price, I’d try it again.Only possible issue in long term usage would be scratching and maybe rust?

I needed something that could hold to the vibration of a 2-stroke engine as the clamp holds essentially what is the intake manifold.I used my rotary tool to bore it out slightly more as the next size up would of been too big. It wasn't impossible with double cut carbide bits, but the metal is definitely hard and dense. Physically speaking, it isn't cheap. If I ever need any sort of collar shaft I will return to this seller.

The device is nice but it rusts and tarnishes. The bolts also rust and can be very difficult to tighten/loosen without a tool. Definitely something enjoyable but will need a replacement very soon after wearing. Time for an upgrade.

Have not used but look quality 👌
