Buying Guide
What to check before buying window crank replacements
- Spindle size: Most parts specify 3/8″ or 5/16″ spindles. Measure your spindle to ensure compatibility.
- Handing and arm length: Determine whether your window requires a left-hand, right-hand, or straight-arm operator and match the length to avoid misfit.
- Material and durability: Die-cast zinc alloy and steel provide strength; plastic options can be lighter and quieter but may wear faster.
- Installation effort: Some units use a simple screwdriver and set screw; others may require minor adhesive or alignment steps.
- Brand compatibility: While universal designs exist, targeted replacements may offer a better fit for older Perma-Shield or Andersen windows.
- Noise and smoothness: Look for 360-degree rotation design and low-friction materials to reduce sticking and squeaking.
