We call it the EleWaiter because it moves up and down and it serves treats. Parrots must turn the "helicopter arm" 6 full revolutions to lower 1 shelf. There are 3 shelves in all. Solid, thick aluminum, stainless steel and brass.
Weighs 1 1/4#. Very sturdy. Recommended for medium to large birds, from Eclectus, Greys, Goffins, etc. to Macaws and Cockatoos.
"Waiter" is 3 1/4 x 3 1/4 and height is 7 1/4 unextended. The waiter adds an additional 3 inches fully extended.
