Do you have a wider jamb bracket for my storm door closer?

Yes, the SK26 is a wider jamb bracket. You can use it to replace the standard one, and it will mount to the jamb using new holes. You should pre-drill pilot holes (1/8") to prevent the new screws from splitting the wood jamb.

There is a drawing showing all dimensions of all our jamb brackets for our storm door closer under SK26, or you can find it below.
