Window Winder White | Right Hand | Lockable – Keyed Alike | 150mm 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 white restricted window chain winder by TradeBase offers smooth functionality, reliable keyed locking, a fixed 150mm restricted chain and a low-profile design that complements light and neutral colour schemes.

Key Features

• Clean white finish — matches white 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 150mm restricted chain — no switch or adjustment, so the restriction can’t be tampered with or left off
  • 150mm restricted opening — lets fresh air in while keeping the opening narrow, adding a layer of security and deterrence when you leave windows open. Like any window restrictor, it’s a deterrent rather than a guarantee against forced entry.
  • Need to meet strata, high-rise or pool-area window opening limits? Choose the 100mm restricted version instead.
• Built to Last:
  • Robust diecast zinc body and mechanism for durability
  • Mild steel zinc-plated chain for everyday corrosion resistance
• Flexible Options:
  • Lockable keyed alike — order two, five or fifty and every lockable winder opens with the same key
  • Compatible with retrofitting older models

Ideal For

• Security while ventilating: keeps the opening narrow as a deterrent when windows are left open — a deterrent, not a guarantee against forced entry
• Ground-floor and low windows: windows within 2m of the ground, where strata/NCC opening limits don’t apply
• Rentals & commercial: limits window swing over walkways and paths
• Ventilation control: stops windows slamming or over-swinging in gusts
