4" Stainless steel refillable goodie basket is a must have for my parrots cages.All you do is unscrew the top.. and stuff lots of oddball toyparts inside, then screw back the top and watch your bird go crazy all day trying to poke thru the bars to get to all the goodies inside the cage.  Hangs from a welded stainless steel 1/2" wide chain and a wide jaw stainless steel quick link lock. The Bar Spacing is 3/4" wide. We added a few surprise toys inside the basket.. but suggest you visit our toyparts section and pick up an assortment of stuffables!
