If any of your basement doors won't stay up and you need replacement Gas Springs here is the manufacturer site:
https://shop.suspa.com/gas-spring-replacements-c17.aspx
The number on the original Gas Spring (at least on mine) is C16-08260
This is a 60 lb Gas Spring.
If you want a little stiffer Gas Spring these are available. Same Gas Spring size just different pressure:
C16-08053 = 80 lb. option
C16-08054 = 100 lb. option
We can never have enough information.
