Window Winder Black 6 Pack | Left Hand | 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.

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. Supplied as a trade 6-pack of six left-hand lockable winders with a fixed 120mm restricted chain — all keyed alike, so one key opens every winder in the set. Restrict a whole floor’s windows in one go, with a single key for the lot.

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:
  • Zinc-plated steel chain
  • Stainless steel fixing screws included
  • Fixed 120mm restricted chain — the window cannot be wound past a 120mm opening
  • 120mm restricted opening for high-rise and upper-storey fall-prevention (NCC). Not suitable for pool-barrier windows, which require a 100mm maximum — choose the 100mm restricted version for pool areas.
• Built to Last:
  • Robust diecast zinc body and mechanism for durability
  • Mild steel zinc-plated chain for everyday corrosion resistance
  • Also available with 304 stainless steel components for coastal and corrosion-prone locations

  • Compatible with retrofitting older models
