25x45mm Frame Packers

25x45mm Frame Packers are compact plastic packers designed for frame fitting, alignment, and spacing during window and door installation work.

With a 45mm length and 25mm width, these Type A frame packers are useful where a smaller packer is preferred around fixing points, tight reveals, or narrow fitting areas. They help installers create a controlled gap between the frame and the surrounding structure, making it easier to level and position the frame before final fixing.

Made from polypropylene, these packers provide firm, consistent support and are suitable for trade use across window, door, and general frame installation jobs.

Why installers choose 25x45mm Frame Packers:

• Compact size for tight areas and smaller frame gaps
• Helps level, space, and align window and door frames
• Useful around fixing points during frame installation
• Polypropylene construction provides firm support
• Can be used individually or layered for controlled adjustment

These 25x45mm frame packers are a practical option when standard or larger frame packers are not suitable for the available space, especially where accurate packing is required in smaller fitting areas.

3mm – General Frame Packing
