Window Chain Winder White | Left Hand | Lockable – Keyed Alike | 300mm Chain | Whitco® Compatible

Covered by a 12 year TradeBase warranty. Every TradeBase window winder is warranted for 12 years against defects in materials and workmanship — in addition to the guarantees you are entitled to under the Australian Consumer Law.

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 window chain winder by TradeBase offers smooth functionality, reliable keyed locking, and a low-profile design that complements light and neutral colour schemes.

Replacing a Whitco® or Other Branded Winder?

• Check the fixing centres first: this winder measures 265mm between screw-hole centres and 280mm overall body length. Measure the hole spacing on your existing winder — if it matches, this drops straight into the same holes with no new drilling.
• Suits timber and aluminium awning and casement windows with butt hinges, hook hinges or non-friction stays.
• Direct replacement for most Whitco®, Stegbar®, Boral®, Dowell®, Trend®, AWS®, Bradnam’s® and Wideline® window winders.
• Not sure? Send us a photo of your existing winder and we’ll confirm the fit before you order.

Key Features

• Clean white finish — matches white window frames and hardware
