Window Winder White | Left 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, and a low-profile design that suits light and neutral colour schemes — with the chain restriction set to 150mm.

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
  • Screwdriver-set 150mm chain restriction — the restriction is set on the base of the winder; once the winder is installed and screwed down there is no switch or adjustment, so it cannot be accessed or altered
  • 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 NCC fall-prevention or pool-barrier compliance? Those require a 100mm maximum opening — see the White Left Hand 100mm restricted version.
• 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
• 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: leave windows open for fresh air while the narrow opening adds a layer of deterrence against opportunistic entry
• Ground-floor and low windows: windows within 2m of the ground, where strata/NCC opening limits don’t apply
• Rentals & commercial: limit how far sashes swing out over walkways and paths
• Ventilation control: keeps the sash restrained so windows don’t slam or over-swing in gusts
