Window Winder Jasper® | Left Hand | Non-Keyed | 120mm Restricted Chain – Replaces Most Winder Brands incl. Whitco®

Non-locking model. This is the non-keyed (non-locking) version — simple, smooth winding with no key required.

Designed to work seamlessly with both timber and aluminium window systems, this Jasper® window chain winder by TradeBase offers smooth functionality, reliable non-locking operation, and a low-profile design that complements a warm, neutral colour scheme.

Key Features

• Genuine Jasper® finish — matches Jasper® frames and hardware rather than a generic 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
• Child safety / fall prevention: the 120mm restricted opening limits how far the sash opens, helping keep children away from open windows
• Compliance: when the restriction is set, the 120mm opening meets NCC fall-prevention (high-rise and upper-storey) opening limits 100%. Not suitable for pool-barrier windows, which require a 100mm maximum
• Easy operation: smooth, reliable winding with a folding ergonomic handle and convenient through-flyscreen operation
• Built to last: robust diecast zinc body and mechanism with a mild steel, zinc-plated chain for everyday corrosion resistance
• Fixings included: stainless steel fixing screws supplied
