I used these hooks to hang Christmas light from an interior steel beam and was so impressed that I ordered 2 more packs!

Worked great for hanging my solar lights along the metal roof of my garage.

I really like these I used it to hang my led strip lights in the backyard...

Im going to try hanging the christmas lights

I used these to hang outdoor patio lights to my classroom's ceiling

Purchased to hang Christmas lights along a metal porch railing on which we didn't want to use anything permanent

Even though we are only hanging Christmas lights at this time, I anticipate that they would hold much more weight than that.

Used to hang xmas lights

Holy Sh*T these are powerful magnets!
