Hello,

What we've recommended in the past is to use the 33-205 threaded nut to reverse install the installation screws on the 39-138 and 39-139 operators. We've installed these with the help of a bench vise; you just press them into the holes at the front of the operator base. Look them over and let us know what you think!

hi. what handle does the 39-139 and 39-138 use? Theres nothing on the description about what handle spline size it has.

Thanks

The 39-114L and 39-205 folding handle under the related items section on the operator's product pages are compatible with these assemblies.
