All our register plates are 1.5mm Zintec and come complete with brackets so that the plates can be fitted to the wall for the register plate to sit on.
If you select the plain register plate you have more flexibility as you can cut your hole wherever you need.
When selecting register plates with pre-cut holes you will not be able to move the position of your flue. Pre-cut register plates also come with removable sweeping access and fixing brackets. They come complete with a plate so that you can fit a 5” or 6” flue.
