Multiple Sliding Door Configurations

Multiple sliding doors come in a variety of configurations to suit your needs. Pocket door configurations are also available. All sliding doors stack panels behind the exterior-most panel.

Configuration code is read from left to right as pictured in the diagram exterior view below. For example, MTS-OXX is a multiple sliding door with the leftmost panel being fixed (“O”) and the other two panels sliding behind it for operation (“XX”).

Pocket sliding doors have an additional letter “L” or “R” at the end of their configuration to indicate to what side the panels slide when viewed from the exterior.

  • “MTS” stands for multiple sliding, and “MTP” stands for multiple sliding pocket
  • “X” stands for operable, sliding panel
  • “O” stands for fixed, non-sliding panel
