SWISCO - The Replacement Hardware Authority

casement window operator

A contractor from Cloverly, MD says:
Looking to replace two right-hand operator units and two left-hand units with the c portion of the arm being 4-7/16ths. What is the correct part number for ordering same. These windows are 20+ years old.

Thank you.

Take a look at our 31-031 and 39-032 operators. They appear to have the same arm configuration as your own hardware. Take a look and compare them just to make sure.
