Frequently asked questions
What is the difference between a customizable lever and a configured set?
A customizable lever is specified by selecting the lever, rosette, function, and finish individually for a per-project quotation, while a configured set is a pre-built package available to order directly. Casson Hardware lists both options on the door levers and knobs page so projects can move between custom and stock workflows.
Which door levers do architects specify for modern residential interiors?
Casson Hardware carries minimalist round-rosette levers, square-rosette levers, and contemporary handle profiles from European and Canadian manufacturers — the lever range most often specified by Canadian and US architects for modern residential projects.
What is the typical lead time for a custom-quoted lever set?
Lead times for custom-quoted lever sets vary by manufacturer and configuration, typically ranging from in-stock to several weeks. Casson Hardware confirms exact lead times at the time of quotation through the specification team.
What functions are available for door levers and knobs?
Casson Hardware stocks levers and knobs in passage, privacy, dummy, and entry function configurations, with the function type confirmed on every product page or at the time of custom quotation.

Casson Hardware stocks levers and knobs in unlacquered brass, satin brass, brushed nickel, matte black, polished chrome, oil-rubbed bronze, and living finishes. Finish availability varies by manufacturer.
