28x80mm Wedge Glazing Packers

28x80mm Wedge Glazing Packers are tapered plastic packers used when a wider wedge is needed to help secure and adjust an insulated glass unit inside the sash or frame.

The 28mm width gives a broader contact point than narrower wedge packers, making these suitable for glazing channels where a wider packer sits better against the glass unit or frame rebate. The 80mm length provides a good working size for everyday glazing adjustments, giving installers enough contact area without being difficult to position.

The tapered shape allows the packer to be inserted gradually, helping take up small gaps and reduce unwanted movement once the glass unit has been placed. These packers are useful for sash alignment, toe-and-heel work, and general tightening where the unit needs to sit more securely before final beading.

Made from polypropylene, WP28A wedge packers are durable, moisture-resistant, and suitable for regular trade glazing use.

Why installers choose 28x80mm Wedge Glazing Packers:

• 28mm width for wider glazing channels and broader contact
• 80mm length for practical on-site handling and adjustment
• Helps tighten glazed units inside the sash or frame
• Useful for reducing play and improving unit stability
• Suitable for toe-and-heel work on windows and doors
• Polypropylene construction for firm, reliable wedging

These 28x80mm wedge glazing packers are a good option when installers need a wider wedge for light or standard adjustment, without moving to deeper taper ranges.

3-5mm – Standard Wedge Adjustment

Used where the unit needs a firmer hold or a more noticeable correction.

• Standard toe-and-heel work
• Reducing movement in opening sashes
