Large bolt-on bottlebrush cage perch for Large Parrots. Made in America from Bottlebrush, a native Florida wood. Bottlebrush has thick, lush bark that won't hurt your bird's feet. It is great for chewing and gnawing, which will keep your parrot's beak shaped and conditioned. These bird cage perches are best for all large parrots such as all large Amazons, Macaws and Cockatoos. Each perch comes with two 2" fender washers and a wing nut to attach to your bird cage. Bird Perch Diameter: 1-1/4" — 2" Bird Perch Length: 12" — 16" Hardware is electroplated and safe for all birds. To install properly, place one fender washer on the bird perch, place the perch inside the bird cage where desired, then put the other washer on the screw outside the bird cage, followed by the wing-nut. Pictures are only representative of the actual item you receive because these are all natural and each perch is unique. The perches will fit within the given specs but no two perches are the same.
