The ND series really are excellent locks. I’ve installed and used a lot of Corbin Russwin grade 1, as well as some grade 2 levers, and of course the ND levers. These look great, work well, and hold up. The Old D series levers were also excellent, but a tad more temperamental as far as installation goes.
