Product Options


Panel sizes are restricted in height and width according to the type of glass used:

  • Maximum panel height: 2600 mm (no more than 800 mm wide).

Maximum panel weight: 65 kg. Special sizes are available on request. Refer to technical literature for panel size diagrams.

Frame finish:

Standard frame finish/ colours: Powder coating, RAL 9016 or RAL 8077; or EURAS eloxal E6 EV1 or E6 C34. Other finishes are available on request.


Standard glazing: Single glazing with 5 mm float glass, or insulating glass units with 2 x 4 mm float glass. Glass upgrade from 5 mm to 18 mm (maximum) is possible. The glass is fixed into sills with a continuous snap-in bead to allow trouble-free pane replacement at a later date. Special glazing methods available on request.

Track system and running gear:

Running and guide tracks are flush-mounted into the system. Low-maintenance, low-rattle, rustproof fittings ensure stability of the system. Height tolerances and expansion are allowed for in the design to prevent operational faults and ensure weathertightness.

Top mounted running gear units each have two universally jointed (cardanic) rollers for even load spread. Trolley bearings run quietly on a sealed, heat and cold resistant running surface of glass fibre reinforced polyamide. The 100 kg capacity trolleys are height adjustable.

– Top track: Extruded aluminium – reference 5-35-01-x.

– Floor track: Extruded aluminium. Available with or without a threshold; can be set into the floor. The design without threshold is for shop fronts or for ‘barrier-free dwellings’ in compliance with DIN 18025.

– Arrangement: Inside or outside stacking.

Ironmongery/ Accessories:

All fittings are corrosion-free and are concealed within the profiles. Panel profiles are connected using die-cast corner fittings with integrated hinge pins.

Panels are latched and unlatched by means of internal flat handles with 180° rotation; lockable handles are optional. Handles available in four RAL colours as standard – other finishes available on request. Aluminium locking bars with minimum 24 mm travel, act on the top and bottom track; bar ends are fitted with polyamide caps to prevent metal to metal contact. Panel connectors are finished in EURAS eloxal in four RAL colours.

Standard ironmongery for entry/ exit door: Handle inside and outside; three point locking handle and cylinder available as an option for greater security and weathertightness. Special pins are provided with inward opening balcony elements, to facilitate cleaning from inside.
