Ladder-Max is the Only OSHA Certified Standoff for Direct Roof Placement. Leaning an extension ladder against house gutters is a common practice. As you well know, this is not only unsafe, it leaves dents, scratches and creases in gutters for years to come. We've all done it. That's why we distribute Ladder-Max. Ladder-Max is the first ladder stabilizer to be certified for roof placement. Placing your Ladder-Max against the roof will avoid damage to gutters, eaves, overhangs and metal siding.
