Casement window weatherstrip with offset kerf

A home owner from Parma Ohio says:
I have casement windows that the hardware says "Entry Gard Truth". The weatherstripping has an offset kerf with a 1/4" diameter foam bulb (see photos attached). The kerf slot in the window measures 1/8" wide. I am not seeing a good replacement on your site. Perhaps the 58-170B would work but I see that it is meant for a 0.078" kerf slot. Is there a different part that may work better? Is there a way to get a sample of the 58-170B or would I need to buy the full 12 foot piece? I am thinking that I could possibly add a spacer to the flat side of the kerf. Thanks for your help.

Hello,

I would recommend looking at our 58-055 bubble seal with an offset base and see if the dimensions could work for your windows specifications. Thanks for posting!
