Blind brackets after turf or turf around them?

I'd lay it down and do your cut outs after install. It way easier than to try and cut out before and slit to fit around brackets. Just makes for a nicer, cleaner install imo.

I just added a new light bar to my Prodigy and measured out where I wanted the brackets and cut it out with a razor knife where I wanted them to go. Piece of cake. then your bracket sits on the deck of the boat and not on the hydro turf.
