MASTERslide  Patio Doors
  The Advance 70 range is complemented by an  in-line patio door, The MASTERslide System that offers stability, durability  and security, all combined within a slimline package.
  This versatile system is available in 2, 3  or 4 panel configurations and can be fitted internally or externally.
  The overall back to front dimension of the  outer frame is 87mm which reduces to 70mm and can connect with the Advance  profile system. Additionally, when installed with a cill, the height of the  outer frame is only 86mm.
  A special stainless steel track that  provides both durability and longevity has been selected for the sliding leaf.  This glides effortlessly on a stainless steel tandem roller which guarantees  smooth operation time after time.
  For porch applications, an optional midrail  is available that can accommodate a letterplate.
  Security is a key consideration with all Rite  Choice System products, therefore, the in-line patio door is further enhanced  with a multi-point locking system and internally fitted beads.
  Other key design benefits include an  anodised aluminium treadplate and ergonomic handle.
  2, 3 or 4 pane options available.
  Optional mid-rail available that can  accommodate letterplate.
