The 30mm width and 80mm length provide a generous contact area that helps spread loads evenly on masonry, concrete, timber and other substrates. This reduces the risk of point loading and movement compared with makeshift shims.

Manufactured from high‑strength plastic, these packers will not absorb moisture or deteriorate over time, making them suitable for both internal and external installations. They are commonly used to level:

• uPVC, aluminium and timber window and door frames
• Kitchen units, bathroom furniture and wardrobes
• Studwork, battens and liners on uneven floors and walls
• Flooring, decking and sub‑frames
• General building components and equipment that require accurate packing

Supplied in a box of 1000, they are a cost‑effective, consistent alternative to using cut‑down timber, offcuts or ad‑hoc spacers on site.

Typical Applications & Use Cases

• Window & door installation
  Levelling and packing frames, sills and thresholds to ensure smooth operation and correct alignment.
• Kitchen, bedroom & bathroom fitting
  Supporting and levelling cabinet carcasses, plinths and worktops on uneven floors and walls.
• Studwork & partitions
  Packing studs, sole plates and head plates to achieve straight, plumb walls and openings.
• Flooring & decking
  Fine‑tuning the level of joists, battens and sub‑frames over irregular substrates.
• General construction & maintenance
  Any situation where small, accurate height adjustments or long‑term packing is required.

Usage Guidance

How to Use Plastic Wedge Packers

1. Place the wedge
   Position one or more wedge packers beneath or behind the component to be levelled.
2. Adjust the position
   Slide the wedge further in to increase height or pull back slightly to reduce height until level is achieved.
3. Check alignment
   Use a spirit level, laser or square to confirm the frame, unit or component is plumb, level and correctly aligned.
4. Secure the fixing
   Fix the component in place with appropriate screws, anchors or brackets, ensuring the packers remain correctly seated.
5. Trim excess if required
   If any packer projects beyond the visible edge, it can be carefully trimmed with a suitable knife where safe and appropriate.

Best Practice Tips

• Use multiple packers to spread loads evenly rather than relying on a single point.
• Combine with flat or horseshoe packers where both coarse and fine adjustment are needed.
• Avoid over‑packing – ensure wedges sit solidly on the substrate without rocking.
• Follow relevant installation guidelines for windows, doors and structural elements.

Key Features & Advantages

• 3–6mm Tapered Profile
  Feature: Gradually increasing thickness along the 80mm length.
  Benefit: Enables fine, controlled height adjustment in small gaps and under frames.
• 30mm x 80mm Footprint
  Feature: Larger contact area than many small shims.
  Benefit: Improved load distribution and stability on masonry, concrete and timber.
• High‑Strength Plastic
  Feature: Tough, non‑absorbent material.
  Benefit: Will not split, rot or rust; maintains thickness under normal installation loads.
• Stackable & Versatile
  Feature: Uniform profile for easy stacking with other shims and packers.
  Benefit: Can be used alone or in combination for custom packing arrangements.
• Trade Pack of 1000
  Feature: Large quantity in one box.
  Benefit: Ideal for regular site use, reducing downtime and the need for improvised shims.

Plastic Wedge Packers 30mm x 3–6mm x 80mm Frequently Asked Questions

1. What are 30mm x 3–6mm x 80mm wedge packers used for?

They are used for levelling and packing items such as window and door frames, kitchen units, studs and joists where small, precise height adjustments are required.

2. Can these wedge packers be used with uPVC window and door frames?

Yes. They are widely used by installers to level and support uPVC, aluminium and timber frames in openings before final fixing and sealing.

3. Are plastic wedge packers load‑bearing?

They are designed to provide stable support under typical frame, unit and component loads when used correctly on a sound substrate. For structural applications, always follow relevant specifications and guidelines.

4. Can I cut these packers to size?

Yes. They can generally be trimmed carefully with a sharp knife if they protrude beyond visible edges. Always cut safely and wear appropriate PPE.

5. Are they reusable?

If removed undamaged, they can be reused. However, in most professional installations they are left in place as part of the permanent packing system.
