Adjustable extension A frame ladder 1.
On Saturday we spent the day at the Mercer Museum in Doylestown PA. It a 6 story cast cement building made in 1913 that primarily displays early on tools and machines.
Anyway they had this current day extension A frame ladder that could be an adjustable height free standing A frame or an adjustable extension ladder that could reach their very high ceilings.
I am not certain why I feel the need to put pics of it in Europa gallery, but think it may be worthwhile knowing about? Fooling with build of glider wings? Storing glider wings in my T hangar that will require hanging them at an angle?
