The ALWAYSFIRST 4 FIXINGS AF4F blue flat packers are designed for trade professionals and DIY enthusiasts requiring precision leveling in window glazing, door installation, and joinery projects. These durable, moisture-resistant spacers ensure structural alignment with a serrated surface that prevents slipping when stacked. While they offer excellent versatility for general construction, users should note that they are strictly for mechanical shimming and do not provide adhesive properties on their own.

Yes, they are made from durable, weather-resistant plastic designed for multiple uses.
No, the serrated design is meant to prevent slippage, but you can use an adhesive if your specific application requires a permanent bond.
Yes, they are waterproof and weatherproof, making them suitable for exterior window and door installations.
These are designed to be rigid and load-bearing, providing stable support for standard door and window frames.
The color-coding system is used to easily distinguish these specific packers from other sizes or brands within the ALWAYSFIRST range.
While they are intended for standard use, they can be trimmed with appropriate cutting tools if necessary.
Ensure the serrated sides are facing each other when stacking to lock them into place, or use a small amount of low-tack adhesive to hold the stack temporarily.
If the gap is not perfectly filled, combine these with thinner shims or rotate the orientation of the stack to better distribute the pressure.
Setup is straightforward: identify the gap size, select the necessary amount of blue packers, and slide them into the target space. For heavy-duty applications, ensure the stack is perpendicular to the load for maximum stability. These packers are compatible with standard timber, UPVC, and composite window and door systems. Maintenance is minimal; after use, simply remove the packers, wipe away any dust or construction debris, and store them in a cool, dry place. Because they are moisture-proof, they do not require special sealants, though users should ensure no sharp debris is trapped between the serrated layers before stacking to avoid uneven load distribution.
