Thanks for the feedback on this ladder. We feel that our locks and hinges are actually one of the strongest points of differentiation for our Multi-position Ladders. Our hinges are 50% larger than comparable ladders, meaning there is significantly less movement and sway in the hinge/lock area when climbing. Our ladders are tested to rigorous standards and we feel they are the safest, most rigid, and most durable Multi-position ladders you can buy anywhere.
