FAQs
Are these packers reusable?
Yes, they are made from a durable material that does not rot or absorb water, allowing them to be retrieved and reused in other projects.
Can I use these for exterior window glazing?
Yes, they are weatherproof and waterproof, making them an excellent choice for external glazing tasks.
What is the thickness of each packer?
Each packer in this specific set has a thickness of 3mm.
Will these packers compress under heavy glass units?
The material is rigid and designed to support standard glazing loads without significant compression.
Are they easy to stack?
Yes, the serrated surface is specifically designed to minimize movement when stacking multiple units.
Troubleshooting
Packers sliding during installation
Ensure the serrated side is facing the surface and consider using a slight dab of silicone or construction adhesive to hold them in position.
Unable to achieve exact gap size
Since the packers are 3mm, use a combination of different sized packers or verify if a thinner/thicker shim is required for your specific tolerance.
Pros and Cons
Pros

- Anti-slip serrated surface ensures stability
- Ideal for both internal and external use
- Lightweight and highly portable

Setup, Compatibility & Care
To achieve the best results, ensure the substrate surface is clean and free of debris before placing the packers. For projects requiring height, simply stack the packers; the serrated design helps them interlock, but for high stacks, consider using a small amount of adhesive if necessary to maintain vertical alignment. Because these are plastic, they are compatible with most standard building materials, including timber, uPVC, and metal. No specialized maintenance is required; simply inspect for wear if removed after long-term installation and reuse as needed.
