Window Winder 6 Pack Black LH Lockable 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 black window chain winder by TradeBase offers smooth functionality, reliable keyed locking, and a low-profile design that suits dark and neutral colour schemes. Supplied as a trade 6-pack of six left-hand lockable winders — all keyed alike, so one key opens every winder in the set.
