These F Type balances are general purpose balances for domestic and commercial applications with a sash weight range of 20.8kgs (46lbs) to 22.6kgs (50lbs). They are fitted with an orange coloured end plug, which refers to their weight range of sash.
These balances are supplied pre-tensioned, reducing the need for adjustment on site. However, fine adjustment can be made “on site” if required using a screwdriver or Allen key.
