Finish options

Sustainability
Built to last - not to be replaced
The most sustainable product is one you never need to buy twice. BLU hardware is engineered for longevity, reducing waste and the environmental cost of replacement over the lifetime of your home or project.
"Good hardware should outlive the building it's fitted to. That's the standard we hold every BLU product to."
