Window Winder Black | Left Hand | Stainless Steel | Lockable – Keyed Alike | 120mm Restricted Chain

Ordering more than one? They’re all keyed alike. Every lockable TradeBase winder in your order is supplied keyed alike — one key opens them all, so you’re not juggling a different key for every window.

Coastal build? The stainless steel chain is the one to fit. In salt air and high humidity, a 304 marine-grade stainless steel chain far outperforms a standard zinc-coated chain — resisting the rust, staining and stiffening that coastal conditions bring. It’s the recommended standard for beachside, coastal and high-humidity homes: fit it once and it keeps winding smoothly for years. If you’re anywhere near the water, spec stainless as standard.

Designed to work seamlessly with both timber and aluminium window systems, this black window chain winder by TradeBase offers smooth functionality, reliable keyed locking, and a low-profile design that suits dark and neutral colour schemes. This version is fitted with a fixed 120mm restricted chain — the window opening is permanently capped at 120mm.

Key Features

• Clean black finish — matches black and dark powder-coated window frames and hardware
• Folding handle — folds flat to sit neatly behind blinds, curtains and furnishings, then swings out for easy winding
• Anti-sag, self-tensioning chain — the self-tensioning design keeps the chain taut, preventing sag and wind-shudder rattle
• Versatile Compatibility: Suitable for timber and aluminium awning and casement windows with butt or hook hinges or non-friction stays.
• Easy Operation:
  • Smooth, reliable operation with a folding ergonomic handle
  • Convenient through-flyscreen operation
• Secure and Restricted:
  • 304 stainless steel chain
  • Stainless steel fixing screws included
