2.750" HEIGHT X 1.694" WIDTH X .553" THICK.
It has a white convex wheel attached 1.375" DIAMETER with a taper step making it to 0.143" THICK that touches the closet rail (the thickness before the taper step is 0.335").
(The height from the top of the gray semicircle to the bottom is 1.985" with a 0.875" diameter hole).
The screw is 0.210" DIAMETER on the threaded area, 1.910" HEIGHT, with a head 0.396" DIAMETER. On the top of the head screw there is a protruded round section of 0.310" diameter with a star shape tool acceptance.
I see you have products 23-225 and 23-199 that look very similar but don't know what the dimensions are.
Thank you so much.
