-–Why is the cut out dimension smaller than the dimensions of the product.? Is it becauce the outer ring is rubber and can contract?—Question for USB-C20-S-VT-CS15-WP-BK Please Put your question below------
Greetings,
Yes, the suggested cutout dimensions would be designed to work with the grommet on the part to achieve the IPx8 rating when mounted.
Thank you, that helps out a bunch.
