product 39-124 1 1/8handle extension

Thanks for reaching out to us. No, the inside of the 39-124 is hollow. It only acts as an extension for the handle, like the 39-116. The screw passes through the handle, through the extension and threads into the operator, like the 39-050 or the 39-234. Take a look at the 39-124 extension along with the related hardware on the website.
