Description
The Kay Otto Fisker Door Lever by d line is a cast solid brass lever designed in the 1940s — one of the most sought-after heritage lever designs, with an iconic, timeless form. The high copper content in the unpainted brass develops a rich patina over time. Rigorously tested for constant commercial use. Made in Europe.
