The Cardinal® Treated Binder ClearVue™ Locking Round Ring Binder does have the mounting on the spine!
This round ring binder holds Legal-Size documents.
Yes, this item is a view binder so it does allow an insert on the front and back.
Great question. The "non-locking" feature in the Avery Framed View Heavy-Duty Binder is a feature that allows you to open the binder rings apart without having to push down on the bottom or top booster. The booster is on metal lever that locks the rings in place so they will not open when the booster is in the locked or closed position. This is a time saving feature that is unique to the Avery Framed View Binders, and considered a value add to this product.
