The Ladder Hook without Wheel by Roof Zone offers a helpful roof ladder hook tool for safe and quick rooftop access. The stationary wheels do not swivel and allow more controlled movement and placement of the ladder over a roof’s peak. This roof ladder hook attaches to the two top rungs of any ladder or ladder extension. To use Roof Zone’s Ladder Hook, simply roll or slide the ladder until the ladder hooks pass the roof’s peak. Two Ladder Hooks offer the best support per ladder. Tie Down Safety maintains high standards and quality control through quality raw materials and components made in the USA.
