How to Choose the Right Balance

1Step 1 Balance number (length)
If you’re replacing a balance, measure the body length of the old unit and match the ‘L’ dimension in the size chart below. For a new top sash, measure the overall sash height including horns (the Closed ‘C’ dimension) and pick the balance whose C matches, or the next smaller. For a bottom sash, measure the window opening height from sill to head (the Extended ‘E’ dimension) and pick the balance whose E matches, or the next larger.2Step 2 Weight range
Weigh the sash, or estimate it from the glass thickness (see the guide below). Match the weight to Range 1 (2.257.25 kg), Range 2 (7.2510 kg) or Range 3 (1014 kg).3Step 3 Foot option
Choose the standard foot attached, or ‘no foot’ to fit an adjustable foot (ordered separately, together with the tension key).4Step 4 Colour
Whitco spiral balances are supplied in black only.

Working Out the Sash Weight

Glass thickness	Weight per m
3 mm	7.5 kg/m
4 mm	10.0 kg/m
5 mm	12.5 kg/m
6 mm	15.0 kg/m
Double-glazed 6+6 mm	30.0 kg/m

Multiply the weight per m by the sash glass area (double the figure for double-glazed), then add an allowance for the sash frame. Best practice is to weigh the sash for an accurate result.
