Re part # 39-247 . Is the bore smooth or does it have 12 splines ?

The 39-247 eyelet adapter is used on Truth operators with a spline size of 11/32 in diameter with 12 teeth on the spline. The 39-247 also has the corresponding teeth to match the operator. Check to see if your skylight is made by Truth hardware. If you want, you can send us some photos of your operator for us to take a look at.
