Tips

For optimal load distribution, position the hook directly over a rafter and use appropriate stainless steel screws. Verify the batten height before installation to select the correct adjustment range. When pairing with K2 rails, ensure the rail is properly seated and secured according to K2's installation guidelines. For slate roofs, consider using a slate bracket accessory to protect the slate and maintain waterproofing.
