Merino Window Winders
A soft off-white match for Merino and light-toned window frames. A low-profile replacement chain winder built for timber and aluminium awning and casement windows.
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 merino window chain winder by TradeBase offers smooth functionality, reliable keyed locking, and a low-profile design that suits a soft, light neutral colour scheme.
