20x60mm Wedge Glazing Packers

20x60mm Wedge Glazing Packers are compact tapered packers used to tighten and secure insulated glass units after the main support packers are in position.

With a 20mm width and shorter 60mm length, these WP20A wedges are useful where the installer needs a compact wedge that can be placed quickly into the glazing gap. They are suitable for 20mm glazing channels and applications where a longer 100mm wedge is not required or where space around the unit is more restricted.

The sloped profile allows the wedge to take up movement gradually as it is inserted, helping the unit sit more firmly within the sash or frame. This makes these packers useful for fine adjustment, toe-and-heel work, and improving the stability of opening sashes, doors, and glazed panels.

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

Why installers choose 20x60mm Wedge Glazing Packers:

• Compact 60mm length for quick fitting in tighter areas
• 20mm width suits common glazing channel sizes
• Tapered profile helps tighten and stabilise the unit
• Useful for reducing glass movement inside the frame
• Suitable for toe-and-heel adjustment work
• Polypropylene construction for firm wedging support

These 20x60mm wedge glazing packers are a practical option when installers need a compact 20mm wedge for controlled tightening and small-to-medium glazing adjustments.

What Each Taper is Used For

1-3mm – Fine Movement Control

Used where the gap is very small and only a light wedge action is needed.

Best for:

• Fine glass adjustment
• Small gaps in 20mm glazing channels
• Light unit stabilisation
• Minor sash correction
• Reducing slight movement after glazing

3-5mm – Standard Wedging & Firmer Hold

Used where the unit needs a stronger wedge action or the gap is more noticeable.

Best for:

• General glazing adjustment
• Taking up medium gaps
• Firmer support inside the sash or frame
• Toe-and-heel work on doors and opening sashes
• Installations where 1-3mm is too light
