## Questions & Answers

**Q: Would this fit a bayonet lampholder?**
A: hi, as long as the B22 lampholder has a 1/2" thread it will fit not a problem.

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.

    Cheap and effective, but....
  

*by D***N on Reviewed in the United Kingdom 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.
