Skylight manual telescopic hardware "(ZON) REG. HOLLAND"

We have recently moved in and have been unable to open this skylight. The end piece was here and fits but is not connected. Wondering if there is a way to fix/ replace that will allow us to operate / open window.
Thank you!

Hello,
Unfortunately, we do not carry exact replacements for the skylight hardware shown in your photos. We do offer eyelets such as the 39-214, 39-247, and 39-214F. We can't be sure if one of them could work for you since our parts are intended to attach to an 11/32" diameter operator spline rather than an elongated screw like yours.
If the set screw is the only broken part preventing you from attaching the original eyelet, you could bring it to a local hardware store to see if they carry a screw that might work with it. I'm sorry that we won't be able to offer more assistance with this repair but please let us know if you have any other hardware questions. Thanks for posting.
