The perches that were bought for these cages came with round clamping washers that are just a bit too small. Instead of reaching 4 horizontal bars, they only touched on 2, barely 3, which isn't enough for adequate support... which makes the perches a little wobbly. And in tightening to correct this, the supplied washers start to bend.
After looking around quite a bit, I finally found a supplier who makes large enough plates. They're on eBay, going by the username "lumberjack1983".
The ones I bought are 1/16" thick steel, 2.75" OD (outer diameter) x 5/16" ID (inner diameter). The inner diameter is the hole where the screw post goes through. It's very important to make sure you measure yours, as some of these screw posts are in different sizes. Installed in place, they worked out great and provide terrific support for the bird with no perch wobble. If you want to get these, just be careful to get the appropriate ID and thickness. 1/16" is more than enough (there is thicker, which is way overkill).
