The COSWALL 86 Type 2 Gang Dry Lining Box is a specialized mounting component designed specifically for hollow wall installations, such as plasterboard or drywall. Unlike standard masonry back-boxes that require chiseling, this unit is engineered to grip onto thin wall panels, providing a secure housing for electrical switches and sockets. With a 35mm depth, it offers a standard clearance that should accommodate most modern electrical modules while maintaining the structural integrity of the wall partition.
At its current positioning, this product serves a niche but essential role in home renovation and electrical infrastructure. With a perfect buyer rating across dozens of orders, it indicates a high level of satisfaction regarding its fit and functional design. However, as with any imported electrical component, the primary focus for the buyer should be on technical compatibility with their specific plates and local building standards rather than just the brand name.
✅ Pros
- Specialized 'dry lining' design allows for clean, easy installation in hollow wall partitions.
- The 35mm depth provides a balanced internal volume for wiring without requiring an excessively deep wall cavity.
- Boasts a perfect buyer rating, suggesting high manufacturing consistency and reliable performance in the field.
- A healthy number of orders for a specialty tool indicates it is a trusted choice among buyers.
Cons and cautions
- International shipping may lead to project delays if you are on a tight construction schedule.
- Lack of stated local certifications means you must manually verify its suitability with a qualified electrician.
- Fixed depth and gang-size limit its use to specific plate configurations.
- Few written reviews (13), so the rating rests on a small sample
- 2 variants on one listing: price and spec change with the option you pick
Who it's for: This is ideal for DIY enthusiasts and professional electricians working on drywall or plasterboard partitions. It is specifically designed for those installing double-sized switch or socket plates who need a reliable, recessed mounting solution without the mess of masonry work.
Who should skip it: This product is not suitable for solid brick, concrete, or stone walls. It is also not intended for users who require specialized local fire-safety certifications that may not be present on international electrical hardware.
🔎 Check before you buy
- Confirm the exact screw hole spacing to ensure it aligns with your 2-gang switch or socket plates.
- Verify the material's fire-retardant rating with the seller to ensure it meets your local electrical codes.
- Ask the seller about the maximum drywall thickness the mounting clips can accommodate.
- Check if the mounting screws are included in the package or if they need to be sourced separately.
💡 Tips
- Always use a spirit level when marking your cutout on the drywall to ensure the box and final plate are perfectly straight.
- Ensure you have a professional-grade drywall saw for a clean edge, which allows the box's flange to sit perfectly flush.
- Before installation, confirm that the power is completely disconnected at the breaker.
