The Large Mitre Block is a precision accessory designed for use with magnetic secondary glazing systems, helping to create accurate, clean mitred corners for a professional installation. It is used in conjunction with steel tape applied to the window surround and plastic capping fitted with magnetic tape, ensuring glazing panels align securely and neatly around the window frame.

Ideal for both new installations and replacement glazing projects, the Large Mitre Block helps achieve a strong, consistent finish while improving the appearance and performance of magnetic secondary glazing systems. Manufactured from durable materials for long-lasting reliability, it is suitable for residential and commercial applications where a precise and professional finish is required.
