This is a plastic strip which holds glass/screen panel in place on our storm door.

We cannot supply an exact replacement for your storm retainer strip, unfortunately. Manufacturers consistently change the design of them, so it is often difficult to keep up with supplying them.

Our best repair option is to use the 70-180 Storm Door Insert Clip, which will require drilling installation holes. You'll need the 70-112 Long Thumb Screw to install it. We have received confirmation that this has worked in many applications but we cannot make any guarantees. Thanks for posting!
