These are identical in size and design in every respect except the 81-156SS shown on top has 1 1/4

I'm afraid this only comes with a 1-1/4" diameter wheel. There was, at one time, a 1-1/2" wheel version, but it is not available. Did you try and see it you could adjust the roller in the 81-156SS to the proper height you need? You might find you can make up that 1/4" difference in the adjustment.
