This is the front left support bracket for a Kraftmaid Roll Out Tray. The tray is 31" wide and 24" deep. Kraftmaid's website does not show this particular support bracket. The one that is shown on the website is not the same shape. The photo showing the removed bracket shows 2 separate pieces. That is where the issue is. It is broken.

We unfortunately don't sell this exact style bracket. However, you may be able to adapt one of our spacers to work as an alternative. Two promising options that come to mind are our 32-339 and 32-334. Look these over and see what you think.
