VELUX Original Roof Window Blackout Blind for S06, S36, Sand, with Grey Guide Rail

Very easy to install. The item that arrived was about 6cm too long for my window (my own fault - GGL MK04 is not the same as GGL M04!!) but I managed to trim the side rails with a hacksaw and take up the slack in the cords. It fits well and there is no light bleeding in at all when it's closed, despite my slight hack job and is definitely a lot better than the third party blind I had in previously :)For anyone interested, there is a little metal bracket inside the end of each side rail that can be slid out and placed into a "trimmed" siderail; so cutting the siderails to fit a shorter window is actually quite straightforward. The most difficult bit was taking up the slack in the cords: on the clip that the cords are attached to, there are two indents on the "wrong" end of each clip; so you can loop the cord around the clip a few times and then lock it in place using those indents. Time will tell if this is a long-term solution, but the blind works fine and the cords stay in place nice and taught under the guiderails.

These blinds are well designed and of the quality you may expect from Velux. They are relatively easy to install with good instructions and all the tools needed. They are easy to operate and do block out the light very well.

I wasn't sure whether I'd go for the OEM blinds at pretty hefty additional cost, but I thought I'd play safe since this is very visible in the room...Upon opening the packaging it looks very good quality, with the runners matching exactly with the existing window and other blinds which were fitted on other windows.READ THROUGH INSTRUCTIONS BEFORE INSTALLING OR PULLING ANYTHIN APART!!!- real important or you could pull apart things which will make installation much much more difficult!!The instructions have no words but fairly easy to follow basically:-- Pushing in top blind section until it clicks on mounts which should already be present on the velux. (If they're not present, there's a bag with a ? on it which provides two substitute clips. I didn't realise this at first and was scratching my head what to do with these at the end!) I had to give it a bit of a gentle bang to get it to clip into place. DONT take off the red bits yet!- Using the provided buttom clips, screw those into place using provided torx screws and torx screwdriver. (Note not to use the clips I mentioned above which are bigger and use the 2-3 philips screws in a bag)- Take the side metal runners and slide them in each side. Before sure they're slide firmly into place at the top before you clip them at the bottom. Hint if you get it wrong, unscrew the torx screw on the bottom clips rather than trying to force the thing out of the clip and potentially breaking the clip.- Once in place, screw the torx screws into the holes along the runners on each side. The torx screw driver should be adequate to screw into the velux wood without need to drill holes.- Pull off the red circles to unroll the cords and then pull out the grey plastic cordends and pull them down to the bottom clips. You'll need to gently stretch them for a moment at you get them to clip into place.- Now at the top take off the red retaining clips at the top and you should be able to pull the blind down- done!Installation took me about 20-30 minutes with careful reading of the instructions. Once done I'm very happy with the results.At £73 vs around £40 for a non-OEM one it's a hefty difference in price. However seeing the quality of this product, and the finish the materials, it's a premium I'm happy to pay for.I'll see over time and update in due course as I use these...

Great blind, easy to fit and cheaper than buying direct from Velux.

As you'd expect from velux, a good product

We’ll designed blind kit with everything needed to fit. Does the job well and is 100% blackout.

Fitted perfectly and very easy to instal.Does the job and looks good.

Bought for GGL-6 windows (had to look at another web site to understand the evolution of velux frame sizes over the year to work out what I needed - shame that information isn't on this page).Warning: Do not pull apart the mounting brackets from their plastic framework until you've looked at all the instructions.There's air-fix style plastic moulds, some bits you throw away, others you use to get the perfect positioning of the brackets and THEN pull the excess plastic off once in place.You get 4 small grey mounts which you attach to your inner window frame first, which come with little spacers attached and a L or R marking on the reverse. So really, if you take 5 minutes to work out the instructions, your life is going to be really easy! As it says, don't detach the red things till the end. I found that on one of my windows, the cable that you stretch down to the bottom bracket was easily done, but not on the other, I had to use quite a bit of force and thought the thing was going to break, but it didn't.These blinds don't go beyond the bottom of the window, so there'll still be some tiny streaks of sunlight, but I could now sleep in my attic in the brightest day without a mask, so does the job very well.You get nearly all the kit you need to do the job, but you will need either an old-school high school compass or hole-making thingy to make a small hole to help the mounting screws go in easily. You will also need a phillips headed screwdriver.Recommended.
