Replacement parts / DESIGN STUDY

Stationary window-crank handle

A keyed hub, offset arm and separate grip bring the shaft interface into one assembly.

Fit the shaft profile

The original stationary reference pairs a round shaft with a flat. The crank hub follows that profile, while the offset arm places the grip away from the hub.

Separate the grip

The waisted grip sits on its own post at the end of the arm. A removable cap makes the grip connection accessible.

Keep each interface editable

The hub, grip and reference hardware are separate parts. Their seats and clearances can be revised independently as a specific application is defined.

Consider the complete handle

The study brings the shaft, arm and grip together as a stationary arrangement for reviewing shape and access.
