weir door replacement

I have a Hayward skimmer that was installed 1978. I need to replace the weir doors which measure 9x4.5 in. If I cannot find the exact measurement on a replacement, can the door be cut to fit? I see a door that measures 8.75 x 5, which means that I would have a little gap on the sides, but the height is 1/2 in too big. Could I cut off the edge?

Welcome to the forum!
See if this listing might show one that works. Or call InyoPools tomorrow to see if they can find one.

As far cutting it, only thing it needs to be able to do is float so that it closes when the pump is off but come down so it assists in the skimming process when the pump is running.
I suggest you read ABC's of Pool Water Chemistry.
