4-Panel Sliding Glass Door Installation & Replacement in San Diego
A 4-panel sliding glass door gives you the width of a glass wall with the simple, dependable operation of a classic patio door. Two fixed panels anchor each end while the two center panels glide open, creating a generous entry right in the middle of the wall. At 360 Windows and Doors, we install and replace 4-panel sliding patio doors throughout the San Diego area, helping homeowners bring in more light, frame their views, and make the patio, deck, or garden feel like part of the house.
What Is an OXXO Sliding Door?
OXXO is industry shorthand for how the panels are arranged, viewed from outside: X marks a sliding panel and O marks a fixed one. In an OXXO door, the two center panels slide past the fixed outer panels in a bypass design, so the opening forms in the center rather than at one end. That makes it a natural fit for wide openings, where a single sliding panel would feel cramped and a walkway through the middle makes the most sense.
Compared with a standard two-panel sliding patio door, a four-panel sliding glass door spans more of the wall while keeping a familiar look and feel. If you’d prefer panels that stack or pocket completely out of the way, a multislide door may suit you better. Our team can walk you through both options.

Frequently Asked Questions
In a 4-panel OXXO door, the two outer panels stay fixed and the two center panels slide to open. In a multislide door, all of the panels move and stack or pocket to one or both sides, creating an even larger opening. An OXXO door is a great choice when you want a wide, centered entry with the simplicity of a traditional slider.

I am so pleased with my new windows and my new French doors that were installed by 360 Windows and Doors! From my first interactions with Eric who worked with me on the quote to Lauren who kept me updated and helped with any questions I had, to Greg and his team of installers who did an excellent job, I was very pleased with the whole experience. They made the process simple and easy from step one. I couldn't recommend this company any higher, five stars all the way!
