Info and measuring guide

Measuring (installation in the window / reveal opening):

Smallest reveal opening width minus 2 cm = order width

The measurement for the order height (exterior) is the smallest reveal opening height, without deduction.

Any cover plates ordered as well (L- or U-shaped) are made 1 cm wider than the blind dimension.

--------------------------------------------------------------------------------

Measuring (installation in front of the window / reveal opening):

Measurement for the order width (exterior) when installing in front of the window opening = window opening plus approx. 5 cm overlap on the right and left = order width of the external blind

Installation on the wall, so that the blind package is not in the window's field of view when raised. Side caps are required for the cover plate, see configuration.

Measurement for the order height (exterior) = window opening height plus package height plus 3 cm = order height of the external blind

The smallest possible width of the blind is 50 cm.

Drive
Info and measuring guide

The most economical version is endless cord / tilting and raising with one cord.

Endless cord (image = projecting gear)

Drive

Projecting gear means that with an order width of e.g. 100 cm, the slats are 100 cm wide and the gear is flanged to the outer edge of the head rail and projects by the gear thickness of approx. 2.5 cm. (e.g. with the endless cord gear)

Flush gear means that with an order width of e.g. 100 cm, the slats are 100 cm wide and the gear is located within this dimension at the outer edge of the head rail and does not project.

Further drive options are motor drive and crank drives, see selection in the configuration.

Side guide
Info and measuring guide

Side guidance with steel cable is recommended as protection against swinging and wind. The steel cable is tensioned at the bottom by means of tensioning brackets in silver (galvanised steel). The steel cable is plastic-coated.

Additional cable guide
Info and measuring guide

This is recommended for blind widths over 2 metres.

An additional punch hole is made in the slats and a plastic-coated steel cable is threaded through. A bracket in a matching colour is supplied for tensioning the cable.

For asymmetrical additional tensioning, please enter the dimension under “Notes”. Please also state from which side you measured. (Left or right, as seen from inside or outside)

Info and measuring guide

The colours available as standard for the bottom rail and the tensioning brackets are silver RAL 9006, white RAL 9016 or anthracite RAL 7016.

For the stated surcharge, we coat the bottom rails and the tensioning brackets (cable tensioners) of the blinds in any possible RAL colour.

The bottom rail is the rail that is visible when the blind is raised.

The top rail is natural silver as standard.

Spacer
Info and measuring guide
Spacer
Info and measuring guide

When using a sun and wind control in conjunction with several venetian blinds, isolating relays must be ordered as well.

e.g.

2 blinds, 1 wired sun/wind control and 2 isolating relays

3 blinds, 1 wired sun/wind control, 3 isolating relays etc.

We supply only high-quality SOMFY controls and accessories. All controls have a switch function. An extra switch is not required. A switch is only required if the blind is to be operated by it alone. Third-party switches can also be used.

We supply the optional radio wall transmitter in an attractive surface-mounted version, type Centralis RTS from Somfy.

We will also be happy to advise you by phone on further radio accessories or controls.

Optionally, we can offer you a 5-channel or 1-channel hand transmitter with scroll wheel (fine slat adjustment). The angle of incident light can be set precisely using the scroll wheel.

or a radio timer in the hand transmitter, type SOMFY Telis 16 RTS

(up to 6 groups programmable)

Accessories
Info and measuring guide

We can supply these fascias in L-shape or U-shape (square-edged).

If you would like the coating in a specific RAL colour, simply enter the RAL colour number under “Notes”.

If you order aluminium angle fascia "YES", we always supply the fascia 1 cm wider than the blind width.

The depth of L-shaped fascias in combination with radio motors is always 130 mm, because with the standard depth of 90 mm the radio receiver cannot be placed next to the head rail.

The depth of L-shaped fascias with all other drive types is 90 mm as standard.

If you need a different fascia width, please enter this under “Notes” or call us on 09732 3023858.

Angle trims as a cover pelmet in white, silver or brown, 1 mm thick = EUR 18 per linear metre, developed dimensions 125 x 100 mm or 150 x 100 mm in L shape, supplied to suit the stack height

Angle trim = L-shaped cover for the top (blind when retracted)

It serves both a visual purpose and as weather protection for the mechanism located in the head rail.

Side cap
Required if you want to mount in front of a reveal opening, in order to close off the cover plate at the sides. (supplied loose)
Call-back service

Product description

Order external venetian blinds with 50 mm aluminium slats here – small stack heights, a wide range of uses and many drive options.

High-quality Reflexa® external venetian blinds with 50 mm aluminium slats, crank or motor operation, made in Germany and of the latest generation (180 degree tilt). At the bottom of this page (below the colours) you will find detailed technical descriptions and PDFs to print out. Prices for external venetian blinds with 50 mm slats are slightly lower than for the wider, flanged slats. Order in our shop and configure your new external venetian blind.

The picture above shows the Reflexa® EMA 50 endless cord blind, which carries out all functions – tilting the slats as well as raising and lowering the blind. During installation the cord is led through the window frame (drill a hole through the frame or wall beforehand) and operated via a deflection pulley (included in the delivery).

For endless cord gears and crank drives we always make the gear flush with the head rail. The pictures show the gear protruding. Changing from "flush" to "protruding" is easy during installation.


Reflexa® endless cord operation is the best-selling version for 50 mm slats.

Endless cord gears are an economical version of the external venetian blind.

- 50 mm external venetian blinds are available with endless cord gear, crank drive, motor drive or radio-controlled motor; the manufacturer is always Reflexa.


Reflexa® motor operation


Crank operation

We offer 50 mm slats up to a width of 500 cm (cord pull up to 300 cm width, endless cord gear up to 250 cm, crank and motor up to 500 cm width) and a maximum height of 360 cm. For larger blind sizes, please choose the 60, 80 or 88 mm slats, which are flanged at the sides.

For protection against wind and weather, the 50 mm blinds can be made with lateral tensioning using a nylon-coated steel wire. For widths over 200 cm we recommend an additional central guide wire (wind protection). To cover the head rail and the slat stack when the blind is raised, an angle cover plate in a matching RAL colour can be fitted on top. The endless cord gear is durable and maintenance-free. Ladder tapes made of 100% Terylene. Head rail always in natural silver, 57 x 51 mm or 40 x 30 mm depending on the drive type. Bottom rail 51 x 20 mm, coated in a colour of your choice. Please note*: with small widths, the blind may hang slightly askew; this cannot be avoided.

Please note: all order sizes are finished sizes of the blind, i.e. outer edge of slat to outer edge of slat = order width, and top edge of blind to bottom edge of bottom rail = order height of the finished blind.

Wall fitting, so that the raised slat stack is out of the window's field of view. Side caps are required for the cover plate, see configuration.

Order height (outside) = window opening height plus stack height plus 3 cm = order height of the external venetian blind

Fitting options: ceiling, wall, recess

Please note that only our measuring guide is binding for you. Any different measuring guides from manufacturers are not valid. We have written ours to be as easy as possible for a non-specialist to follow. If you have any questions, please call our telephone hotline.

The following slat colours are available. Other slat colours can be supplied on request at no extra charge – just ask. Head rail always in silver. The bottom rail and tensioning brackets of the blind are silver, dark grey or white as standard. All other colours are available at a surcharge, see configurator.

We are happy to send you the stack heights and specifications of the individual slat types on request.
