Pair of old or antique cast iron pulleys... originally these were for window sash weights, but now they would be good for clothesline, garden gate closers and more.
These are marked Andersen and measure 2" across the pulley wheel and 4 3/8" long. They are made for 5/16" diameter rope.
We're not sure of the exact age of these pulleys, but Andersen Windows started making windows in 1904 and we'd guess that these are close to that.
These pulleys have a patina of age and old paint.
