This is off one of five that will need hinge sets and operators . I don't believe they are Caradco as there is no secondary arm to move the hinge. There have been others repaired with Caradco parts with a shorter operator arm and with the seconday arm to move the hinge and the second attaching bracket. I can see the part number 20755 as well as Truth Entry Guard stamped on the replacements.
If Caradco parts will work, how do I determine correct placement of the secondary bracket which moves the hinge?
