Hi, folks. I have a Confer Plastics 7200 series ladder. It is rated at 300lbs max. I'm about 270 and when I climb the thing, the rungs bend considerably, particularly the ones outside the pool. I'm sure the sun isn't helping, though I don't think it's making a drastic difference. I make it a point to step as close to the outsides as possible, but still they flex as if the ladder was rated for 200lbs.
Now, I realize this thing is just molded plastic, but there's gotta be a way to improve it. I'd like to try and fill the hollow rungs with something. My first thought was structural expanding closed cell polyurethane foam, however, the foam kits are very expensive. It's not available in a can like you'd find at Lowes. Second, I thought of concrete or some sort of high strength grout, but wasn't sure if I could get such a viscous product into the cavity without considerable surgery. Third, was Bondo body filler, but I run into the same issue as concrete.
Yes, a wood ladder/stairs w/platform would be the best solution (maybe someday) but I really like the ladder in general, particularly the roll-guard feature. It's lightweight and maintenance free. It's also the least visually obtrusive option, IMO. Now, if I could just stiffen the rungs.......
I understand this may not be the best place to ask this question, but I'll give it a shot.
