+Adapter West (For use with The Grease Box GX-U Sold Separately)

I have the Yoder ys640s with an UNDER-MOUNT drawer So my grease box cannot bolt on flush with the grill. This +adapter west is a quick 5 min install and sealed off the part of the grease box that protrudes past my grill to give it a nice finished look.
Thank you for the great customer service!
