## Summary description

UN KB8 Type III plastic mounting wedge set (25 pieces) with size specification 8/30/60 mm. Designed for precise leveling and spacing in installation tasks, these plastic wedges support alignment of doors, windows, frames and panels. Durable, lightweight and resistant to common site stresses, suitable for construction and renovation use.

## Long description

UN KB8 Type III plastic mounting wedges, pack of 25, are designed for precise leveling and spacing in installation tasks. Each wedge features a stepped profile with nominal dimensions 8/30/60 mm to allow fine adjustment between building elements. Made of durable, lightweight plastic, these wedges are intended to support alignment of doors, windows, frames and panels during assembly and finishing work on construction and renovation sites.
Advantages
The wedges provide consistent thickness increments for incremental adjustments and eliminate the need for improvised shims. Their plastic composition offers resistance to moisture and common site stresses while remaining light to handle. Supplied as a pack of 25, they enable repeated use during single projects and fast placement and removal without special tools.
Suitable for
Leveling and aligning door and window frames during installation
Positioning panels, trims and joinery before fastening
Temporary spacing for sealing, glazing and insulation work
Small renovation and carpentry tasks requiring controlled gaps
When it may not be suitable
These plastic wedges are intended for temporary adjustment and spacing; they are not designed to carry long-term structural loads or replace engineered supports. For heavy-duty structural shimming or permanent load-bearing applications, metal or engineered shims specified by a structural engineer should be used.
Key specifications
Material: plastic (durable, moisture-resistant polymer)
Stepped dimensions per wedge: 8 mm, 30 mm, 60 mm (nominal thickness steps)
Pack quantity: 25 pieces
Primary use: leveling, spacing and alignment for installation tasks
How to use
Place the wedge between the elements to be aligned (for example, frame and wall or sash and frame) and slide or tap gently until the desired gap or level is achieved. Use the appropriate step on the wedge to obtain the required thickness; multiple wedges can be combined for larger gaps. After fasteners, sealants or adhesives are set, remove the wedges if a removable shim is required, or trim and leave in place if the installation specification permits non-structural permanent shims.
What to consider before purchase
Confirm the required thickness steps (8/30/60 mm) match your leveling needs
Verify that plastic, non-structural wedges are acceptable for your application
Ensure pack quantity (25 pieces) is sufficient for the scope of work
Usage recommendations
Use wedges on clean, dry contact surfaces for best grip; avoid relying on them for permanent load-bearing support. Store in a dry place away from direct sunlight to maintain material properties.
