Fitting coving is a tough enough task for most DIY home owners. To help with that task, and essentially we are talking about cutting the mitres on coving, there are a couple of options. These are coving mitre boxes, coving mitre tools and cornice jigs.
We have an article on how to install coving, which is worth reading. As mentioned this can be tricky enough, and that is if you know exactly what you are doing. You will also know that you may need a mitre saw or a mitre box to make the important angled and compound cuts.
A coving mitre box along with a fine tooth hand saw is the cheapest and best combination for cutting mitres in coving. These were invented due to the popularity of fitting coving. They basically take the complications out of making the wrong cut and that avoids many hours of frustration.
You just need to be sure that the mitre box you purchase is wide enough for the type of coving that you have bought. A lot of coving is 127 mm and most mitre boxes don't cater for that size. We have listed below those that do.
