Lockable Window Winder White Birch RH 300mm

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 Birch® window chain winder by TradeBase offers smooth functionality, reliable keyed locking, and a low-profile design that complements a soft, warm neutral colour scheme.

Key Features

• Genuine White Birch® finish — matches White Birch® frames and hardware rather than a generic white winder
• 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 Adjustable:
  • Zinc-plated steel chain
  • Stainless steel fixing screws included
  • 300mm maximum opening
  • Chain restriction switch included — limits the maximum window opening for child safety and fall prevention
  • Adjustable chain restriction — set the switch and the window opening meets NCC fall-prevention (high-rise / upper-storey) opening limits 100%, plus helps satisfy swimming-pool barrier requirements (AS 1926.1). A simple compliance fix for homeowners, landlords and strata managers
• 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
