Pocket doors used to be incredibly popular in homes in the 1800s. However, they used to run along poorly built tracks that actually crossed the walk path, rather than inside the wall, resulting in a trip hazard. This led to pocket doors gradually being phased out by builders over safety concerns. But thanks to modern solutions, like the pocket door kits available from Runners, all equipment is hidden seamlessly inside the wall cavity, creating an attractive and perfectly safe disappearing door effect.
