It needs to be bigger to protect against squirrels Indeed can protect feeder from rain but not if strong gales, only light rain ON feeders smaller than the drip line (diameter) of this dome

Mine measures 17" in diameter.
Yes, the plastic should withstand a jigsaw or keyhole saw. I don't have the baffler any more but the plastic is fairly thick and strong.
It should fit if you take care to vacate the entire insert. No problem with cracking yet. Don't know about winter and freezing conditions.
