Guys my ladder is a 1A rated ladder for 300lbs but I weigh 330 and Im 6'5" tall. I know you're thinking damn he's fat but I just want to tell you that it all turns to ____ at midnight! I think exceeding the weight limit is ok when your not 20ft in the air but do these ladders have a safety factor that anyone knows about? I plan on doing some nice size houses and I don't want to come crashing down. Thanks!
