What Are Plastic Wedge Packers?
Plastic wedge packers are small, tapered shims crafted from high-strength, weather-resistant plastic. Their primary function is to provide adjustments and fill gaps during construction, ensuring accurate spacing and leveling between structural components.
Key qualities of premium plastic wedge packers:
– Manufactured from heavy-duty, non-compressible plastic
– Weather and rot resistant, suitable for interior and exterior use
– Consistent, precise sizing for dependable results
– Easy to cut or stack for custom applications
Our 30mm x 3-6mm x 80mm wedge packers (1000 pack) offer exceptional quality—perfect for trade professionals seeking bulk reliability or homeowners tackling major renovations.
When to Use Plastic Wedge Packers
Wedge packers are versatile and widely used across various construction settings. Some common applications include:
–Window and Door Installations: Ensuring frames sit perfectly square and level for smooth operation and a tight seal.
– Timber Framing and Cladding: Achieving flush, even surfaces and managing natural variations in wood.
– Floor and Deck Levelling: Adjusting joists, battens, and boards to eliminate uneven spots.
– Wall Panel Spacing: Preventing movement, vibration or bowing in drylining and cladding.
– DIY Home Repairs: Leveling appliances, mounting shelves, or correcting skewed bathroom furniture.
Their precision, durability, and ease-of-use have made them a construction staple—replacing less reliable materials like timber offcuts, which can compress or rot over time.
Step-by-Step Guide: How to Use Plastic Wedge Packers for Leveling
1. Assess the Installation Area
Begin by cleaning and preparing the area where packers will be inserted. Remove debris, dust, loose material, or old shims to ensure solid contact with both the component you’re leveling and the supporting structure.
2. Measure the Gap or Area Needing Adjustment
Use a tape measure, caliper, or laser level to determine the size of the adjustment required. Knowing the gap size helps you pick the right packer thickness (our 30mm x 3-6mm x 80mm wedges offer incremental adjustment between 3mm and 6mm).
3. Select the Appropriate Wedge Packer
Choose the size that best matches the required spacing or leveling. If a custom fit is needed, you can stack multiple packers or cut one to size.
– For small or narrow adjustments, use the thinnest end of the wedge.
– For larger adjustments or filling irregular gaps, stack two or more wedges with tapered ends facing opposite directions to create a stable, even pack.
4. Insert the Wedge Packers
Gently tap the wedge packer(s) into place using a mallet or hammer. Don’t force the packer—apply only enough pressure to bring your material or frame into level.
– For window and door frames, place packers around the perimeter (usually at each corner and midway along the sides), so the frame is evenly supported and balanced.
– For decking or flooring joists, insert packers under the low spots, then check again with a level.
5. Check for Level and Alignment
After positioning your packers, re-measure and use a spirit or laser level to confirm you’ve achieved the correct alignment. Adjust as needed, adding or removing packers to fine-tune.
6. Secure Your Components
Once everything is level and square, continue with fixing, screwing, or sealing as required for your project.
– For windows and doors, secure the frame with screws before fully tightening—test that it opens and closes smoothly first.
– For floors, ensure all boards are firmly in place before nailing or screwing down.
7. Leave In Place or Remove (as Project Requires)
In most installations, plastic wedge packers are left in place—they don’t rot, compress, or interfere with materials. If temporary spacing was required, they can be removed after fixing.
Tips for Best Results
– Use Multiple Packers: For large gaps, stack wedges with opposing tapers for maximum stability.
– Avoid Timber Offcuts: Unlike wood, plastic wedge packers won’t swell, shrink, or rot.
– Precision Matters: Always re-check with a level or square after inserting each packer.
– Choose Quality: Inferior packers can crush under load—use high-strength products like our 30mm x 3-6mm x 80mm wedge packers.
Common Mistakes to Avoid
– Over-tightening Screws Before Checking for Level: This can pull the component out of square, resulting in incorrect alignment even if you’ve used packers correctly.
– Using Incorrect Thickness: Always measure the gap beforehand to avoid uneven support.
– Placing Packers Only in Corners: For frames and floors, supporting at corners only may cause long-term bowing or sagging—add packers at intervals along the length.
