Roller wheel is metal and seems 1 1/8 inch diameter. Length of housing is 2 1/4 inch. Height is 1 1/4 inch. We need two of these. One for each end of the door. Door seems to be original to the house which was built in 1981. Not sure what other information you need.

Hello! Based on the photos you have provided I would suggest the Lupton Roller Assembly 81-269. Take a look at the dimensions for the 81-269 and let us know what you think.
