Q: well, ive had my scaffolding for nearly a year and its all healed, but today when i tried to move it (slide the bar back and forward) it felt like the bottom hole was really tight around the bar. Ive got a bigger bar than i need so its not too tight. any help would be appreciated! :-) thanks all x: that happens. it's nothing to worry about. it should relax a bit with time. if you really need to move it, a little water-based lube, like ky jelly, will help.
