About this part
What it is and why it is made that way
These lever brackets carry a visible finish as well as a function. Investment casting produces a smooth surface straight from the mould, so the part needs far less finishing than a machined equivalent, and the pivot points are machined to keep the movement free. A polished or plated finish can be applied on request.
- Smooth mould surface — minimal finishing required
- Pivot points machined to the specified fit
- Polished, brushed or plated finish available
- Stainless, bronze and brass options
