Product Information
Full details
The Magflap MK3 is designed for homeowners seeking to immediately stop cold draughts, reduce heat loss, and eliminate letterbox noise. Its key benefit is a powerful magnetic seal that creates a tight, silent barrier, unlike traditional brush strips. A potential consideration is its standard fit, which may require an optional rear gasket for highly irregular surfaces.

FAQs
How do I know if the Magflap MK3 will fit my door?
The Magflap MK3 is designed to fit standard UK letterboxes and is compatible with most wood, uPVC, metal, and composite doors. Measure your existing letterbox aperture to confirm.
Can I install the Magflap MK3 myself?
Yes, installation is designed to be straightforward and typically takes about 10 minutes with basic tools like a screwdriver. No specialist tools are required.
Will it stop my cat from coming in through the letterbox?
The Magflap MK3 is designed to stop draughts and noise, not to prevent pets from entering. For pet security, consider dedicated pet access solutions.
What maintenance does the Magflap MK3 require?
Minimal maintenance is needed. We recommend occasional cleaning with a damp cloth to keep the surfaces clean and ensure the magnetic seal remains effective.
How is it different from a brush draught excluder?
Unlike brush excluders that can wear out and become less effective, the Magflap MK3 uses a precision magnetic seal for a consistent, silent, and long-lasting closure.
Can I install it on the outside of my door?
Yes, the Magflap MK3 offers flexible internal or external fitting options depending on your door setup and preference.
What are the optional add-ons for?
The optional rear gasket is for doors with protruding bolts or uneven surfaces to ensure a better seal. The internal locking key set prevents tampering and letterbox fishing.
Troubleshooting
Weak magnetic seal
Ensure the metal plate on the opposing side is clean and free from obstructions. Check that the Magflap is correctly aligned with the letterbox opening. For doors with significant thickness or irregular surfaces, consider using the optional rear gasket.
Draught still present
Verify the Magflap is installed correctly and fully covering the letterbox aperture. Check for any gaps around the unit itself and ensure the cork gaskets are properly seated. Ensure you have the correct model for your letterbox size.
Noisy operation
The magnetic closure is designed to be silent. If noise persists, check that all screws are tightened and that no parts are loose. Ensure the letterbox flap itself is not the source of the noise.
Difficulty closing letterbox flap
This may occur if the Magflap is installed too tightly or if the letterbox flap has a very strong spring mechanism. Loosen the mounting screws slightly or ensure the Magflap's internal components are not obstructing the flap's movement.
