Need a larger backplate that normal?
This is the solution, a 50mm diameter Brass backplate. Ideal if you need to add a lampholder to a wooden surface where there is a larger hole to cover up. This backplate can cover a hole that is 25mm approx. diameter.
There is a 10mm male thread to allow you to fit any 10mm lampholder. Sorry we cant supply a nut cover for this large backplate.
You will need 3 screws that will fix in the 2.4mm fixing holes.
Plate diameter: 50mm
Plate Height: 1.6mm
Thread Diameter: 10mm
Thread Height: 6.5mm
Fixing Hole Diameter: 2.4mm
