Nailing studs that are to carry a lintel
When nailing studs that are to carry a lintel, avoid nailing into the upper section of the
stud that will soon be cut out to accommodate the lintel.
Fitting a door head in a timber framed wall
If the wall has a door in it you will now need to fit the door head and head trimmer. A
door head is a piece of timber, normally 90 × 45, that will be fitted horizontally between
the door studs onto which wall lining etc. will be fixed over the door. The head trimmer is
a short piece of timber that is fitted vertically between the door head and the top plate.
The length of the door head was written on the top plate earlier.

Total opening height
2089 rounded up to 2090
This height is the height from the underside of the door head to the bottom of the
bottom wall plate.

Calculations to establish the height of the frame door head
Mark the required height of the door head on the door studs and fix it in position,
ensuring that it is square to the door studs.
