I needed to remove my security screen to install a space filler on the bottom. I didn't see any way to do this alone till I seen an instruction video using these to mount the door. I never could have done the job alone without these.  I then used them on a bathroom door that had split.  I took the door down, squeezed in Gorilla Glue and used the clamps to press the crack closed for a couple hours. I love these clamps and I see lots of use in my future home improvement and honey do projects.
