Thanks Spares2you for repairing or restoring lamps online. **Q: What is the diameter of the internal bore please?** A: Without striping the fitting down I could not say, however from memory I would say about 7-8 mm. **Q: anyone know if there is a e27 lampholder that would fit this backplate ?** A: Yes any of our Half Inch entry E27s will fit this backplate. https://www.amazon.co.uk/dp/B01LQOZNGO?th=1 We also stock Batten E27s which have a larger integrated skirt and footprint for an all-in-one solution. **Q: I want to attach to 22mm coper pipe do you have a size for that? Thanks** A: If you look it up on Amazon under that name, you will find the platet is 25mm. You should be able to swage the tube out slightly with a the rounded jaw end of closed big pliers by twisting them round inside of the pipe, or devise something conical. 1.5mm is all that will be required. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Well made brass fitting *by M***S on 3 July 2023* Great product for lamp wooden bases. Enables fitting of the lamp holder and is sturdy and looks good. ### ⭐⭐⭐⭐⭐ Good quality and arrived promptly. *by M***E on 17 June 2019* Looks perfect for the job. I haven't used as didn't need but keeping in case I need for another project. ### ⭐⭐⭐⭐ Cheap and effective, but.... *by D***N on 21 October 2017* Nice little product, worked fine. The screws don't seem to be a perfect fit, they do fit, just not that neat a job. I'm pretty sure the screws supplied were not the ones in the picture but they are never seen so, for the price, fair enough. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/51333939-back-plate-nipple-fitting-1-2-threaded-brass-boss-25mm](https://www.desertcart.co.uk/products/51333939-back-plate-nipple-fitting-1-2-threaded-brass-boss-25mm) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-14*
