Llave para tuerca de anclaje

Hi frustred, Thank you for your question about the Delta Faucet RP93495 Anchor Nut Wrench. I am sorry this information was not readily available, and I am happy to help! This wrench is included with faucet models 3574-MPU-DST and 3564-MPU-DST. The wrench tightens the EZ anchor mounting assembly so the valves can be installed above the sink, saving your knees and back. See the installation and maintenance manual for more information. https://media.deltafaucet.com/MandI/77310%20Rev%20I.pdf Please contact us directly if you have any questions or need additional assistance. We appreciate your business and look forward to continuing to serve you! Best Regards, Bryan Digital Communications Specialist
