Identify Your
MCC Bucket Type
Not sure what MCC you have? Use this visual guide to identify your bucket type by the handle mechanism. Once you know your type, we can build the right replacement.
Quick Identification Tips
Check the Nameplate
Look for a manufacturer nameplate on the MCC structure door or side panel. This usually has the model info you need.
Look at the Handle
The handle mechanism is the easiest way to identify bucket type. Each manufacturer has a distinctive design.
Measure the Bucket
Standard widths are 20". Heights are typically 6", 12", 18", 24", 36", or 48". Measure carefully.
Take Photos
If you're still not sure, take clear photos of the handle, door, and any nameplates. We can identify it for you.
