The size of the chain used on 1950s vintage chain pull heat vent dampers typically varies, but a common size would be a #6 ball chain, which has a bead diameter of approximately 1/8 inch (3.2 mm). If you have an existing chain, you can measure the diameter of the beads to confirm the size. If you are looking to replace or restore a vintage chain pull heat vent damper, using a #6 ball chain would be a good starting point.
Typical usage for beaded chain:
#6 - for lamps & ceiling chains
#8 - drive chain for vertical blinds,
#10 - plumbing applications,
> #13 - Industrial Chain
