40x80mm Wedge Glazing Packers

40x80mm Wedge Glazing Packers are extra-wide tapered packers designed for glazing systems where a large contact surface is preferred but only light adjustment is required.

The 40mm width gives these wedges a broader face than most standard wedge packers, making them suitable for wide glazing channels, larger sealed units, and installations where the packer needs to spread contact across more of the unit edge.

Unlike deeper wedge packers used for heavy gap take-up, the WP40 range focuses on shallow, controlled adjustment. The 1-3mm and 2-4mm taper options are useful when the glass unit is already close to the correct position but needs final tightening, slight movement reduction, or a small alignment correction before beading.

Made from polypropylene, these packers are durable, moisture-resistant, and suitable for professional window, door, conservatory, and curtain walling glazing work.

Why installers choose 40x80mm Wedge Glazing Packers:

• Extra-wide 40mm profile for very wide glazing channels
• Broad contact area for larger sealed units
• Shallow taper options for controlled final adjustment
• Helps reduce slight movement inside the sash or frame
• Useful for sash alignment and toe-and-heel fine-tuning
• Suitable where a wide wedge is needed without heavy lift
• Polypropylene construction for firm trade use

These 40x80mm wedge glazing packers are a good choice when installers need a very wide wedge for light-to-standard tightening rather than deep gap filling.

What Each Taper is Used For

1-3mm – Fine Wide-Channel Tightening

Used where the unit only needs a small amount of wedge pressure across a broad contact area.

Best for:

• Final glass positioning
• Small gap correction
• Light movement reduction
• Fine sash adjustment
• Toe-and-heel finishing work

2-4mm – Light Adjustment & Controlled Hold

Used where slightly more tightening is needed while still keeping the adjustment shallow and controlled.

Best for:

• Light unit stabilisation
• Small-to-moderate local gaps
• Wider glazing channels requiring a broad wedge
• Door and sash alignment
• Installations where a deeper taper is not required
