Vent: guy in Toledo told me never to use a power stretcher on stairs, now I'm second guessing 12 years of work
Was doing a 3 room job in Toledo last month and this old timer watched me set up my power stretcher at the bottom of the stairs and said flat out 'you're gonna rip that backing, I've seen it 100 times.' I've been using it on steps for 12 years with no callbacks, but he had me wondering if I've just been lucky and the knee kicker is the safer play. Any of you run into this, do you stretch stairs by hand or let the machine do the work?
