We don't carry a trim kit for fitting the Norcold N2175 into an N621 opening. Most installers build a simple wood frame or filler strips to close the gap around the smaller fridge, then seal the old roof and side vents. Compare the N2175 cutout with your opening to see how much filler you'll need.
If you have any questions, just reach out at info@rvfridgeguys.com or call us at 800-712-8822. You can find everything we carry at www.rvfridgeguys.com.
