You are looking at a Penn Elcom die cast aluminium lever latch, powder coated black.
The dimensions can be seen in the second photo.
If you have any questions about the latch please feel free to message me and I will try to answer promptly.
Postage will be combined and discounted for multiple orders.
I have lots of flightcase fittings and other equipment for sale in my eBay store.
Thanks for looking!
