Review: Great product - Great product described perfectly. Shipped and arrived in good time.
Review: Really Useful Project Box - The box is well made, and the access screws allow you to chose to hinge the lid. The box is exactly the right size for the project I am building into it, and the thickness is sufficient to accept self-tapping screws and - more importantly - the 3mm tapped hexagonal posts with the self-tapping screw on the non-tapped end...and I brought those posts as I knew I would need them ...but at the time I didn't know what for! At least I knew what I was buying this box for - an intruder alarm for my son (he's not paying ADT THAT much anymore!)

## Questions & Answers

**Q: Can a din rail be fitted into this enclosure?**
A: yes you can mount your din rail in

**Q: Does this come with hinged screws or not? There appears to be conflicting information.**
A: The screws themselves are not hinged, they become a 'hinge' when partially undone. The heads are held captive to allow the lid to 'hinge' on them. So to use the hinge function - undo and remove the two uppermost screws, them partially undo the lowermost screws to allow the lid to open and rest on them. the lowermost screws can naturally be fully removed to allow the lid to also be fully removed.

**Q: Is the internal dimension 300mm x 220 less in the corners due to the lid screw housings? i need to fit in a pcb which 294 in length and 200 in width.**
A: yes that is correct 300x220 less the corners.
your PCB is too big for this box

**Q: Can a ns32 / ts32 terminal rail be fixed directly to the back of the box?**
A: Yes
