Hi folks, the pneumatic closer attached to the bottom of my storm door split the bottom of the jamb where it was attached. See the picture.

I am trying to figure out repair and future prevention.

I could glue the split piece and patch up the jamb, but the closer will destroy it again.

Is there some sort of a C shaped metal plate that I can attach to the bottom of the jamb to make it strong?

Something like this?

This product goes further than making a C around the middle of the jamb. It's pricey and I don't like the sleeve mechanism.

Any ideas on reinforcing the bottom jamb?

I thought of moving the closer to the top of the door, but I see the previous owners had put a similar closer there before (see four holes on the top of the jamb) and the closer will probably destroy the jamb there.

I can't put the closer in the middle of the storm door.

Thoughts?
