Fopr [censored] years I have struggled with garage door that

door scrapes along the concrete.

I have been moving it on a pipe, but want to do something
less primitive.

Do they make anything that can be *screwed to both sides
of the door and has good-sized wheels to move door more easily?

TIA

Adjust the hangers or shorten the door?

The only "off the shelf" bolt on casters assemblies that I am aware
of ... .... have swivel wheels & spring loaded shafts .... not
exactly the best set up for your application
