25x100mm Frame Packers

25x100mm Frame Packers are long, narrow plastic frame packers designed for accurate spacing and alignment during window and door installation.

With a 100mm length and 25mm width, these Type B frame packers provide extended contact along the frame while keeping the packer profile narrow. They are especially useful where a longer support point is preferred, but the installation only requires a fine 1mm adjustment.

Made from polypropylene, these packers are rigid, durable, and suitable for professional frame fitting work. They help installers create a controlled gap between the frame and the opening before final fixing.

Why installers choose 25x100mm Frame Packers:

• Long 100mm profile for extended support along the frame
• Slim 25mm width for controlled packing in narrow areas
• 1mm thickness for fine spacing and minor correction
• Useful for window and door frame alignment
• Helps maintain an even gap before fixing
• Durable polypropylene construction for trade use

These 25x100mm frame packers are a good choice when you need a longer packer for frame support, but only require a small thickness adjustment.

What the 1mm Thickness is Used For

1mm – Fine Spacing & Final Frame Adjustment

Used where the frame is already close to the correct position and only a very small correction is needed.

Best for:

• Fine frame alignment
• Small gap correction
• Final adjustment before fixing
• Layering with other packers for exact spacing
• Maintaining a neat, controlled frame gap
