I got this to replace a similar ring compressor that broke after about 50 years of service. It has a wide range of adjustability to fit most common engine bore sizes. Just install the rings on the piston, wrap the ring compressor around and tighten it up, and carefully drive the piston home. It helps to oil the piston and rings so they easily slide against the surface of the ring compressor and cylinder wall. This unit seems to be of equal quality to my old one, so I expect it to outlive me.
