Roll-out shelf

A roll-out shelf, also known as a glide-out shelf, pull-out shelf, sliding shelf, or slide-out shelf is a shelf that can be moved forward in order to more easily reach the contents stored in the back of a cupboard or cabinet without having to bend over. They may also save space, as they can be installed closer together than fixed shelves.

Patents for roll-out shelves exist at least as early as the 1800s.
