Description

Our XL Mitre Box is a professional cutting tool designed for accurately cutting both traditional plaster cornice and lightweight cornice. Built for larger decorative mouldings, it helps you produce clean, accurate 45° mitre cuts for a professional installation.

With a maximum capacity of 255mm projection and 275mm drop, this Mitre Box is suitable for many of the larger cornice profiles used in period properties, restoration projects and modern interiors. The robust design securely supports each moulding while cutting, helping to reduce movement and improve accuracy.

Unlike standard mitre boxes, the XL Mitre Box is designed to handle both fibrous plaster mouldings and lightweight polyurethane, duropolymer and polystyrene cornices. As a result, it is the ideal choice for professional installers, restoration specialists and DIY users working with a wide variety of decorative mouldings.

The adjustable guides help hold the moulding securely in position while you cut. This produces cleaner mitres, tighter joints and less material waste, saving both time and money during installation.

The XL Mitre Box is suitable for cutting:

  • Plaster cornice
  • Lightweight cornice
  • Coving
  • Ceiling mouldings
  • Wall mouldings
  • Picture rails
  • Dado rails
  • Decorative architectural mouldings

Whether you’re installing handmade plaster cornice in a period property or fitting lightweight mouldings in a modern home, this Mitre Box provides the accuracy and stability needed to achieve professional results every time.
