20x100mm Wedge Glazing Packers

20x100mm Wedge Glazing Packers are tapered glazing packers designed for installations where a longer wedge is preferred for unit tightening and adjustment.

The 20mm width suits many common glazing channels, while the 100mm length gives a longer bearing area along the edge of the insulated glass unit. This makes them useful when the installer wants a more even wedging action than a shorter wedge can provide.

The tapered shape allows the wedge to be inserted gradually into the glazing gap, helping to take up movement and hold the unit more firmly within the sash or frame. They are useful for toe-and-heel work, door and sash alignment, and general glazing correction where the unit needs to be stabilised after the main setting packers are in place.

Made from polypropylene, WP20B wedge packers are durable, moisture-resistant, and suitable for professional glazing installation work.

Why installers choose 20x100mm Wedge Glazing Packers:

• Longer 100mm body for steadier wedging pressure
• 20mm width suits many standard glazing applications
• Helps tighten glazed units inside the sash or frame
• Useful for toe-and-heel adjustment and sash alignment
• Helps reduce movement after the unit has been positioned
• Polypropylene construction for firm, reliable adjustment

These 20x100mm wedge glazing packers are a good choice where a standard 20mm wedge is needed with extra length for smoother, more controlled unit adjustment.

What Each Taper is Used For

2-4mm – Light Wedging Over a Longer Area

Used where the unit needs gentle tightening with a longer contact surface.

Best for:

• Fine glazing adjustment
• Small gaps in 20mm channels
• Light sash stabilisation
• Toe-and-heel fine-tuning
• Reducing minor movement without over-tightening

4-6mm – Firmer Adjustment & Stronger Hold

Used where the gap is larger or the unit needs a more positive wedging action.

Best for:

• More noticeable gap take-up
• Door and sash alignment
• Stronger unit stabilisation
• Reducing movement in opening sashes
• Installations where a 2-4mm taper is not enough
