My neighbor had a kitchen drawer rear bracket break. It does not screw into place, but is a friction fit into two predrilled holes into the back of the cabinet. Manufacturer is unknown.They appear to be me from plastic/nylon. They were installed approximately in 2006-2007 after hurricane Katrina He believes the cabinets with drawers were purchased from Home Depot. The bottom supporting portions broke.
Any assistance you can provide will be much appreciated. I have searched the internet with no luck. Perhaps the bracket has been reengineered?
Blessings,
Scott
