We offer both flat jambs and rabbeted jambs. However, we highly recommend flat jambs because of internal stability and superior veneer face materials. 
In special circumstances where you do not have enough jamb space to attach your screen door or for new porch construction we can help you out by making jambs and pre-hanging your screen and storm door. 
You can choose to have you screen door pre-hung on jambs with or without seals.
