Mighton UK3.Installing Balances

Note that the shorter pair of balances is normally for the top sash, given sashes fo equal height. With the sashes lowered, insert the appropriate pair of balances into the grooves (fig 8). In the case of unequal size sashes it is possible to slightly bow the balance for the insertion into the groove of the larger sash. In some cases, larger sashes may have to be removed.

Fit the top of the balances to the frame jamb at the centre of the groove tight up against the frame head, with the flat of the foot atachment against the jamb. Fix using woodscrews provided (Fig 9).
To attach balances to sashes, firstly raise the sashes as high as possible and prop in position. The foot attachment at the bottom of each balance should now be visible. Using pliers or vice grips, pull the foot attachment straight down, sufficiant to clear the spiral rod protruding from the lower end of the balance. (fig 10)
Now fold the foot attachment under the bottom rail of the sash and carefully release the tension of the balance (Fig 11).

Using the woodscrews provided, fix the foot attachment to the underside of the bottem rail, ensuring that the balance is kept tight to the sash. *Fig 12).

Mighton UKAlternative method
For unequal sashes, very heavy sashes and/or sashes with horns.
Before inserting balances into the grooves, tie a loop of strong cord or wire around the foot attachment as shown (Fig 13)

Proceed as previously described, using this loop to pull the foot attachment downwards and across under the bottom rail of the sash. Fix using woodscrews provided, before fully tightening screws, remove the cord or wire from the foot.

.For sashes with horns, using standard horn channel attchments(pre fixed in Section 1 Fig 4 and Fig 5) use the loop to pull the balance foot down so that it can be located into the bottom of the channel and then carefully released (Fig 14). Remove the loop of cord or wire
