Door fitting field notes / UK

Measure first. Mark once.

Record the job before cutting, drilling or lifting. The Marked Door turns door measurements into a clear setting-out sheet, with the method and limits kept beside the numbers.

Choose by the job in front of you

Start with the opening, symptom or mark.

Choose the single page that owns the question. Each worksheet keeps its inputs, limits and sources beside the result instead of turning several different jobs into one vague calculator.

The working sequence

Measure

Take more than one reading.

Record the position as well as the number so a variation is not hidden.

Mark

Transfer from one datum.

Keep offsets and assumptions on the same sheet as the marks.

Check

Pause before altering material.

Compare the record with the relevant maker instructions and the actual job.

What this resource does

A worksheet, not an installation verdict.

The tools record entered values, expose their assumptions and stop when required data is missing or implausible. They do not inspect the opening, certify workmanship, select a product or replace the instructions supplied for a particular doorset.
