Hello Bmw2466, Thanks for your question! The RP72751AR includes the side sprayer and hose assembly. It does not come with the mounting for the side sprayer. I hope this helps!

Hi Nafta07, Thank you for your question. Here is a link to the faucet model 2497LF-RB installation manual that uses the RP72751RB. The quick connect connection gets pushed onto the stud coming down from the faucet. http://www.deltafaucet.com/customersupport/documentation/2497lf-rb.html?document=mi&fromDetailArea=kitchen&documentIndex=0#flashWrapper Thanks, Dave
