Window Chain Winder White | Left Hand | Stainless Steel | Lockable – Keyed Alike | 100mm Restricted 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.

Coastal build? The stainless steel chain is the one to fit. In salt air and high humidity, a 304 marine-grade stainless steel chain far outperforms a standard zinc-coated chain — resisting the rust, staining and stiffening that coastal conditions bring. It’s the recommended standard for beachside, coastal and high-humidity homes: fit it once and it keeps winding smoothly for years. If you’re anywhere near the water, spec stainless as standard.

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. Specified for high-rise apartments and pool compliance where regulated.

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.
