Installing a dry lining box looks straightforward, but getting it right first time can save a lot of frustration and unnecessary damage to the wall.
In this video, we take you through the correct method for cutting in a 1-gang dry lining (dryline) box, although the same technique applies to 2-gang boxes and other similar plasterboard back boxes.
You'll learn why it's important to do more than simply draw around the box and start cutting. We demonstrate how to use a bradawl to check for hidden timber or metal studs before making the cut, helping you avoid one of the most common installation mistakes.
We also cover:
How to accurately mark out a dry lining box
Why leaving around 50 mm between adjacent boxes is good practice
Checking for hidden studs before cutting
Ensuring the fixing lugs have enough room to open correctly
Using a pad saw to achieve a neat, secure fit
Tips for preventing paint from chipping on decorated walls
Fitting the box so it sits snugly in the plasterboard
Whether you're an electrical apprentice, college student, DIY enthusiast, or experienced electrician looking to refresh your skills, these simple techniques will help you produce a professional finish every time.
