Selling my Lori's 2a since I upgraded to an 8C. Specs: Overall length: 2 3/8" Base ring: approx 1 1/2" - 1 9/16" Inner cage diameter: 1 1/8" Full disclosure I made some modifications to it: filed down the internal pins on the base ring and cage so it is a smooth ring and smooth cage opening. Also I cut a slot in the end of the cage to make using the washroom easier. I think I did a good job at the edits, but it could use some polishing just to make it shine for looks. $400 US, shipping included .
