The Janser AST-30 Aluminium Retractable Door Rule is a professional measuring and marking tool designed to capture accurate doorway and threshold widths before flooring materials are cut.
Its adjustable aluminium body extends from 60cm to 100cm, allowing the rule to be expanded directly across a doorway for a true threshold measurement. The measured width can then be transferred onto the flooring material to help produce accurate cutting lines and a cleaner finished fit.
Accurate Doorway Measurements
Expanding the rule directly between the sides of the doorway provides a reliable physical reference, helping avoid awkward tape-measure readings and reducing the risk of transferring the wrong measurement.
