Window Sash Balances  are in stock at Progressive Controls Pty Ltd.

We keep stock of spiral sash balances (or ‘window spirals/springs’) for double-hung timber windows and aluminium windows.

Of course, we carry other window and door hardware too; Some items are quite common and others are a little rarer, e.g. another rare stock line we keep in-store are casement window winders (for steel windows that are hinged left or right & swing on the horizontal axis).
