Product Information
Full details
The Primaflow Plastic Pattress Box (45mm, Double) is designed for electricians and DIY enthusiasts who require a reliable, deep-set mounting solution for double-gang electrical faceplates. Its primary benefit is the increased internal volume, which simplifies the management of bulky wiring and connections behind the wall surface, though its 45mm depth necessitates a wall cavity or surface-mount depth sufficient to accommodate the protrusion.

FAQs
Is this box suitable for outdoor use?
No, this is intended for indoor use. Outdoor installations require specific IP-rated enclosures.
Does this box come with mounting screws?
Usually, the pattress box is supplied as the housing; you should use the screws provided with your specific electrical faceplate.
Can I use this for flush mounting in a brick wall?
Yes, provided you have chased the wall to a depth of at least 45mm to accommodate the box.
What is the material made of?
It is constructed from high-quality, flame-retardant grade PVC/plastic.
Will this fit standard 25mm shallow back-box replacements?
Only if your wall depth allows; this is a 45mm deep box, so it will protrude much further than a standard 25mm box.
Troubleshooting
Faceplate does not sit flush against the wall
Check for excessive cable density behind the faceplate or ensure the box is mounted deep enough into the wall cavity.
Screw threads stripping
Ensure you are using the correct diameter machine screws; if the plastic threads are damaged, you may need to use a slightly larger self-tapping screw or an insert.
Pros and Cons
Pros
- Generous 45mm depth simplifies complex wiring management
- Durable, impact-resistant plastic casing
- Universally compatible with standard double-gang faceplates
- Cost-effective solution for both trade and residential projects
Cons
- Requires significant wall depth for flush mounting
- Plastic material may crack if over-tightened with power tools
- Not suitable for fire-rated wall requirements
Setup, Compatibility & Care
Installation should be performed by a qualified professional or a competent DIYer, ensuring all mains power is isolated before starting.
- Mark the mounting position using the box as a template.
- Ensure the substrate (wall) can accommodate the 45mm depth.
- Secure the box using appropriate wall anchors or screws through the molded mounting points.
- Use the provided knockouts for cable entry, ensuring protective grommets are used if required to prevent abrasion.
Maintain the product by checking that the faceplate screws remain tight over time, as thermal expansion and contraction can occasionally cause minor loosening.
