Window Winder Surfmist® | Right Hand | Lockable – Keyed Alike | 150mm Restricted Chain – Replaces Most Winder Brands incl. Whitco®

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 Surfmist® 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 a fixed 150mm restricted chain.

Key Features

• COLORBOND® Surfmist® finish — matches Surfmist® and light 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 150mm restricted chain — the restriction is built into the chain, with no switch or adjustment to tamper with
  • 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? See the 100mm restricted version, which meets the required 100mm maximum opening.
• 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
