34x50mm Frame Packers

34x50mm Frame Packers are Type I installation packers designed for accurate frame spacing, support, and alignment during window and door fitting.

With a 50mm length and 34mm width, these packers provide a wider contact area than many compact frame packers, while still being easy to position around fixing points. They are useful where installers need a firm spacer behind the frame to help keep it plumb, square, and correctly supported before final fixing.

The U-shaped design allows the packer to be placed around the fixing area, helping support the frame as screws or fixings are tightened. This helps reduce the chance of the frame being pulled out of shape and supports a cleaner, more controlled installation.

Made from polypropylene, these packers are durable, moisture-resistant, and suitable for professional frame installation work.

Why installers choose 34x50mm Frame Packers:

• Wider 34mm packer face for stable frame support
• Useful around window and door fixing points
• Helps maintain consistent frame gaps during fitting
• U-shaped design allows fitting around the fixing area
• Helps reduce outer frame distortion when fixings are tightened
• Suitable for window and door installation work

These 34x50mm frame packers are a good choice when installers want a compact but wider support packer for controlled frame positioning.
