Centre opening sliding doors have been the traditional configuration for larger openings, however with the development of modern sliding door technology that has allowed for much wide panels this style has become less popular. We can still manufacture doors in centre-opening configurations, and there are still times where this is absolutely the right choice, however in this design the widest section of profile (including the locking mechanism for the doors) is the element right at the centre of the opening, right in the middle of your view out. In addition this configuration only allows for a 50% opening when the doors slide back, compared to a massive 75% opening that can be achieved using a 4-panel system with 3 sliding behind a fixed frame at one end.
