Eurospec Big Brass Mortice keys - We keep both genuines and copies and there is half a gauge difference between the two. Many of our customers keep both and just match the customers original (ie if the customer brings in a copy then use a copy).
Always found it a bit bizarre.
Davenports ESPC6 is their version of the JMA TX13D. They have just put the eurospec round head on it rather than the Mila / Versa style square head.
We keep both in stock, along with the Eurospec and Mila genuines.
I am not a big fan of the duo machines, they are not designed to do any real volume of key cutting and often fall short of customers expectations.
You will get a Rekord for the roughly the same money or if you can afford it the Bravo Pro is worth the extra.
They are definitely harder, but we cut a fair amount to code for our trade customers and the success rate with the genuine blanks is much higher than any copies.
I personally would rather send out a product that I was confident was going to work even if it costs me slightly more in cutters.
The practice locks is a great idea we have them here too.
We also sell genuine Yale blanks too, we have the best results with them. They are also cheaper than the Silca and JMa blanks too! work that out?!
