Hello, thank you for posting, It appears you have a older style operator where the cover is not removeable. To use a cover and handle like the 39-452, you would need to replace the full operator with the 39-220B depending how the dimensions compare. The cover is plastic and the handle is diecast metal. Please review and let me know if you have any additional questions! |
