Money saving tip.. My Hood model 810 vintage 1984 furler was real sluggish. Almost took 2 to roll in the 150. Called the factory and they said.. probably bad bearings, we can refurbish in 24 hours.. I probably dismantled more than I needed in getting it off.. but shipped out today. Price is about 10% of a new one. So off it has gone. Sure is good when the factory supports old hardware.
