Hello, What size hole do I need to cut for this grommet for a proper fit, and should I radius the corners?? Thanks

The Optronics Flush Mount Grommet for A91 and AL91 Series Trailer Clearance and Side Marker Lights # A91GB, will fit a hole that measures 2-7/8 inches across and 1-1/2 inches tall. You will want to round the corners for a snug fit. This rubber grommet gives shock mount protection that extends the life of the lamp.

I have included a video review of this part for you to check out.
