Got to admit, I have not read all the posts, so if anyone has already brought this up, sorry for repeating. So envisage yourself erecting a six foot lift ( no matter what height the scaffold) you loose the fitting, it swings around and smashes you in the knee cap or bolllocks, either one is going to hurt like fuuck? good idea but stop the pendulum motion before the product is introduced. This idea/product will be introduced to all height scaffolds once it takes hold, so inventor, please, don't forget the users welfare.
