When you are opening a canopy and sliding the legs open a ball pops into a hole to adjust the height.
It is a spring and ball assembly. What's it called ? Where can you buy them?
Can you get them in much larger sizes?
Building new repair shop, block walls. Would like to put a design (mural etc.) on inner wall (walls). Don't want typical 2 or 3 different paint colors (red, gray, white). Walls will be white. Any ideas?
