Thank you for your question regarding the Delta Slide Mechanism and I am happy to assist you today.
This slide mount, RP64155CZ, will fit on bars with a 3/4" diameter.
We manufacture a mount which can fit on the 41624-CZ bar, model U6500, although it is not available in a Champagne Bronze finish at this time and I apologize for the inconvenience.
Please feel free to give us a call if we can assist you with anything else going forward at 800-345-3358.
