Centor S4 Cornerless System

Open more of your home to the outside with the Centor S4 Cornerless System. Designed with the same clean lines as our S4 Straight-line System, homeowners will enjoy even more fresh air and views, with each side of the opening capable of spanning up to 4679mm wide. Operating with just a fingertip, Centor’s unique load balancing technology allows screens and blinds to glide smoothly across the whole door opening to effortlessly stop at any desired position. When not in use, the screen or blind retracts discreetly into the frame removing visual distractions to the view outside whilst also protecting it from damage, dust or dirt.

  • Pair with new or existing post-less doors or windows.
  • Operates from any height with one hand so the youngest of family members can operate the screen.
  • Screen and blind fabrics are held securely in place by top and bottom tabs, preventing screen blow-out – even in a breeze.
  • The screen and blind are fully retained within the frame on all sides to allow total control of insects, sunlight and privacy. 
  • Screen mesh is available in a choice of different weave styles with no pleats or sliding panels to detract from the view.
  • Luxury blind fabric is available in light-filtering and blackout with a choice of stylish patterns and a range of colours to suit every home.
  • Screens and blinds are available in four configurations to suit any home.
  • The durable aluminium frame can be powder-coated in any colour for full personalisation.
  • Can be mounted on the inside or outside – drainage holes are added to the sill for externally mounted systems. 
  • Sill cover is quick and easy to remove to make cleaning trouble free.
  • Backed by a 5-year limited warranty.

* Fabric widths are established by fabric thickness. Variations in fabric thickness may mean the maximum width can not be achieved. In these cases we offer an alternative colour or fabric type or an extended lead time to allow fabric to be resupplied from the mill. All screens over 5910mm in width require frame joiners to support the head and sill. Click here for more information.

Installation

S4 can be specified for new doors or windows, of any brand or composition; it can also be retrofitted to existing doors. Its 44mm sill height allows S4 to be easily aligned with finished floor level. The system can be easily installed on the inside or outside of the opening. Sill drainage holes are provided for systems positioned on the outside to allow water to flow out of the door drainage. The drainage holes are not visible and won't block holes in the existing door sill.
