FAQs
Are these packers rot-proof?
Yes, they are manufactured from high-quality, synthetic materials that are completely rot-proof and do not absorb moisture.
Can these be used outdoors?
Absolutely, they are weatherproof and suitable for external glazing and joinery projects.
Can I use these for heavy-duty doors?
Yes, they provide excellent structural support for door installation, provided they are placed at load-bearing points.
Do I need to glue them together?
Not usually, as the serrated surface provides enough friction for most jobs, but you can use adhesive if you need a permanently fused stack.
What is the primary material used?
They are made from durable, rigid plastic designed for long-term compression resistance.
Troubleshooting
Packers sliding when stacked
Ensure the serrated surfaces are facing each other; the texture is designed to interlock and minimize lateral movement.
Difficulty maintaining level during heavy installation
Apply a small amount of construction adhesive between the packers if a permanent, immobile shim stack is required.

Setup, Compatibility & Care
To use these packers, simply place them under the object being leveled or spaced. When extra height is required, stack the packers directly on top of each other; the serrated surface will naturally interlock to increase stability. No special tools are required for installation. Compatibility includes most standard window, door, and flooring materials. For care, these packers are virtually maintenance-free. Because they are waterproof, they do not require sealing or treatment. If they become dirty on a job site, they can be rinsed with water and wiped clean before being stored for future use.
