Help replacing older door roller

A home owner from Florida says:
Hi,

My house was built in 1964 patio doors look original. Need new rollers but these seem to have a spring adjustment. Do you recognize them? know who made them? Have any or can refer me to who might?

Thanks for your help

I believe you might have an older Daryl/Plaza patio door. Your roller looks very similar to the 81-062 in shape and size. Take a look at the measurements we provide on the item webpage, and see what you think. Will our part replace yours?
