Our 6" Faceplates and larger, are constructed using cast iron. This enables us to re-enforce the outer diameter with a 1" wide x 1/4" thick rim. This rim is connected to the hub with four ribs tapered to the full length of the hub.

The result?

A superior faceplate that has maximum stiffness with minimum weight. Eighteen holes are then drilled to take up to #10 screws, resulting in what we feel is a breakthrough design for the best face plates available anywhere.

Please note that these part numbers are very similar to Stronghold Adaptor Part Numbers, so when ordering, also include a short description for clarity.

If the thread size of your spindle thread is not listed, we can do special custom threading.
