XM FITNESS Preacher Curl Attachment

No it is different hole configurations and length of the shaft.

Hi Roger,The inner tubes of our Xtreme Monkey preacher and leg extension add ons are also 1 3/4 inch. The holes along the tube will run left to right instead of front and back. They are designed to be used with our XM100 FID Bench and will be at your own discretion if you decide to purchase it for the Keys Fitness bench. Kind Regards

Hello EricThis is meant for the XM 100 bench and unfortunately is not compatible with your bench. We do not sell any attachments compatible with the Fit505 Adjustable FID Bench V2.0

Hello,The Xtreme Monkey Preacher Curl Attachment is not compatible with the Golds Gym unit as it is an add on that is exclusive to the Xtreme Monkey brand.
