screen door spring

A quick learner says:
I would be buying the 86-021 spring for a thirty year old screen door. Is this spring the right one? Are they universal? Do you carry exterior door handles for the storm door itself? Mine is old and tanished. Also wondering IF originally this ssliding Pella door didn't have some type of weather stripping between slider and stationary part of door, If so mine is missing and would like to replace.

Paul from SWISCO responded:
This spring is for a sliding screen door not a storm door. Take a look at the storm door section for the hardware you need. SWISCO does carry a replacement storm door chain and here is the installation guide for the 40-036 storm door chain: I am not sure if Pella sliding doors had any weather stripping but you can take a look at the weather stripping catalog section .
