I have been given some s/h telescoping ladders and they seems like some sections are stuck somehow. You *can* release each section and most sections will slide open and closed reasonably well but some are very stiff / stuck.
I think they might be an earlier version of these (but look to be the same mechanical design):
I can't see any obvious signs of damage or distortion, except some sections seem to have a light vertical score down the outside as if some screw or pin might have been set or moved too far in on the collars?
There is also what looks like be the remains of some white paint on the back of a couple of sections and I'm sure that wouldn't 'help'?
I was wondering if anyone had seen similar 'sticking' and knows if you can take such things apart to clean / lubricate / service etc?
My interest is mainly for that, for the s&g's. If they do respond well and appear 100% I might keep them for my own low level use (excuse the pun) but I didn't want to scrap them if there was a chance they could be fixed (properly).
