Searching for B16291Y27B2M split arm operator

Hello,

It looks like your windows use either our EntryGard 39-031 and 39-032 or Caradco 39-155 and 39-156 operators. To choose between the two sets, you'll need to measure you smaller link arm and compare it to the dimensions shown on our product pages, since the link arm is the main difference between the Caradco and Entrygard operators. Thank you!
