3030 Profile End Cap

End cap with tight fitting, so it will stay on the profile without any additional fixtures. The end caps I found so far all have loose fittings, so they either need to be attached to the frame with screws or need to be glued down. This end cap can simply be pressed on the end of an aluminum 30x30 profile.

Note, that the tight fit will wear off, so this article is basically intended for a one-time use.
