Read instructions carefully before installing balances. It is recommended that before balances are installed the sashes are glazed, and in the case of timber windows, all painting is completed ensuring that both sashes slide freely in the frame.
While sketches show timber windows throughout, fitting instructions apply to all types.

It is important that the balances used are suitable for the weight of the sash. They are manufactured in three weight groups and identified by a number, 2, 4 or 6 stamped on the sprial rod (see fig 7)

D2 : is for sash weights up to 68kg (15lb)

D4: for over 68kg (15lb) up to 13.6kg (30lb)

D6: for over 13.6kg (30lb) up to 18.1kg (40lb)

Raise the sashes as high as possible and prop up. Fix foot attachments ensuring that spiral rod is located between sides of fitting.
