Q: What does the Can Rotator price include?

Answer:  The $29.95 price is for each separate can rotator device.  Some of the pictures show multiple devices mounted next to each other.

Q: How are the devices secured to a wall?

Answer:  As they can be quite heavy when fully loaded, they need to be securely screwed into a wood backing - either a solid sheet such as plywood or several horizontally mounted boards which are screwed into studs.

Q: How much clearance is required underneath the devices to allow the removal of the cans?

Answer:  1.5" to 2" is recommended underneath them if multiple devices are mounted next to each other.
