50mm Flat Glazing Packers

50mm Flat Glazing Packers are wide-format plastic packers designed for applications where maximum support width is required during glazing installation.

At 50mm wide and 100mm long, FP50 packers provide a broad bearing surface beneath sealed units and frame sections. They are useful for wider glazing rebates, larger units, door systems, conservatories, and curtain walling work where a smaller packer may not offer enough surface coverage.

Made from polypropylene, these packers are firm, durable, and moisture-resistant. They help installers lift, level, and position units accurately while providing a stable support point under load.

Why installers choose 50mm Flat Glazing Packers:

• 50mm wide profile for a large support surface
• Useful for wide rebates and larger glazing systems
• Helps create an even base beneath sealed units
• Suitable for windows, doors, conservatories, and curtain walling
• Rigid polypropylene material for dependable trade use

These 50mm glazing packers are ideal where the job calls for a broader flat packer and a stable base support point across wider frame or glazing systems.

What Each Thickness is Used For

1mm – Fine Setting & Final Adjustment

Used for small corrections after the main packer height has been set.

Best for:

• Final unit positioning
• Fine height adjustment
• Small gap correction
• Layering with thicker packers for precise spacing

2mm – Light Levelling & Small Spacing

Useful when only a slight lift or correction is required.

Best for:

• Minor levelling work
• Small gaps under sealed units
• Light spacing in wide rebates
• Fine adjustment during installation

3mm – Standard Wide-Packer Support

A practical thickness for regular glazing and fitting work.

Best for:

• Everyday sealed unit support
• General window and door installations
• Routine spacing and levelling
• Building up packer height in controlled layers

4mm – Medium Gap Correction

Used where a moderate height adjustment is needed beneath the unit.

Best for:

• Medium gap filling
• Levelling larger glazed units
• Supporting units across wider frame sections
• Correcting uneven base areas

5mm – Larger Lift & Load Support

Provides extra height and firmer support for larger or heavier units.

Best for:

• Larger installation gaps
• Heavier sealed units
• Door and conservatory work
• Base packing beneath wider units

6mm – Maximum Thickness for Firm Support

The thickest FP50 option, suitable for installations that need a stronger lift or heavier support point.

Best for:

• Deeper glazing rebates
• Heavy-duty support areas
• Large window and door systems
• Raising units to the required installed position
