Thank you for your question regarding the Delta Pin Shower Arm Mount and I am happy to assist you today.
This shower arm pin mount is not compatible with the 24" Adjustable Glide Rail Wall Bar, model 55511-PK and I apologize for any inconvenience this may cause, although the replacement slide bar mount, BAS4BX, will be compatible with the slide bar.
Please feel free to give us a call if we can assist you with anything else going forward at 800-345-3358.
