This is a dual fixture with two apertures 120mm apart.
The carrier is skimmed (3mm) so that the bezel fits flush in to the carrier using magnets. This gives the bezel a clean finish against the plaster.
The fixture has an 18mm deep black baffle and white powder-coated outer bezel. This product contains a baffle which stops 0.8mm short of the bezel resulting in improved lighting compared to a full-length bezel.
