Bosa Onyx Vertical Blind
A solid black colour, the Bosa Onyx Blackout Vertical blind is a dramatic addition to a room, capable of casting it into total darkness. The back and front of the 89mm louvres match, which is not always the case on blackout blinds but is most definitely a plus in this case. It is fire retardant and PVC free, making it ideal for any home and application. ...read more
Sometimes you just need some peace of mind when you come to place an order for your blinds. With DotcomBlind’s Right-Size Guarantee you can have just that. With our Right-Size Guarantee we will replace a blind with the correct size if you get the measurements wrong when you order.
Why do I need this Insurance?
We can’t accept returns or provide refunds for blinds that are mismeasured because all of our blinds are made to measure and so the onus is on the customer to get the measurements right for their blinds. Sometimes you might just be having an off-day, get your centimetres and inches mixed up and end up with a blind that is nigh-on useless. With our Right-Size Guarantee we will take that blind back, remake it to the correct size for you and send it back, saving you from having to buy a totally new blind!
How does it work?
✔ Purchase Right-Size Guarantee when you place your order
✔ If one of your blinds has been measured incorrectly, get in touch with us within 14 days and we’ll tell you how to return the blind to us.
✔ Once your blind is with us, we’ll remake it or adjust the blind to your correct measurements and send it back.
✔ Please read our terms and conditions for full details as you will incur additional costs returning the blind to us.

How to Measure
Now, you can’t mess this one up. It’s what we call ‘easy’ here at DotcomBlinds. But just in case you need some help, follow this quick guide.
First thing's first, identify whether your blind is going inside or outside of a recess.
Inside the recess
A recess fit blind means you supply us with the width and drop of your recess – from top to bottom and wall to wall. We make deductions to account for the brackets to ensure your blind fits within the recess perfectly.
To measure a roller blind to fit inside the recess of your standard window, simply measure the full width and the height of the recess. Then input those measurements into the product page with your order selecting the ‘recess’ option. We’ll do the rest, leaving you the well-deserved excuse to put your feet up, you worked hard for it after all!
Don’t be tempted to deduct any measurements, we do this for you. Make sure you use a metal tape measure; a cloth one can stretch and give you more millimetres per centimetre than a pound-shop ruler. Also, take your measurements in three places and give us the smallest (if there is a smallest). You will find that some recesses shift and settle over time.
Outside the recess
A blind going outside of a recess is usually called an exact fit blind. An exact fit blind means we won’t make any deductions to the width or drop measurements. Exact fit is the bracket to bracket measurement and is commonly found installed outside of a recess. The size you give us is the size your blind is made to.
If you want your blind to hang outside the recess, measure the height and width but be sure to add some overlap to reduce light leakage. This overlap should be about 70mm at the top and bottom and 50mm each side, ensuring you suffer no dazzling strips of sunlight once your blind is happily installed. Please select the ‘exact’ size option when ordering.
Choosing the best control option for you
We provide two control options with our vertical blinds, meaning you can choose the right means of operating your blind to suit your needs, location of the window and the room you choose to install it in.
A chain operated vertical blind is an easy way to operate your blind and how much light enters your room. This function is particularly helpful if access to the whole blind is limited. Simply stand to one side and use the cord. The smooth operation and stylish chain provide an easy and safe way to enjoy your blind.
A wand operated vertical blind allows you to move your blinds to exactly where you want them and adjust the louvres with a simple twist of the wand. The lack of cords or chains make this method of operation incredibly child safe. We have designed our wand operated vertical blind with ease of use in mind. A wand operated vertical blind is the easiest way to operate a vertical blind.
Ensuring our products are child safe is a priority for all of us at DotcomBlinds. As a result, our blinds are child safe by design, with built-in safety mechanisms to help reduce the risk of an accident. These mechanisms specific to vertical blinds are:
• All chains provided with our products are made at a maximum length of one metre
• Chain tensioners (or p-clips as they're also known) and cord tidies are supplied with every chain and cord operated blind
We offer a Child Safe Plus feature with our vertical blinds, which is an upgrade to remove the chain mechanism and replace it with a cordless means of operating the blind.
The wand operated function of the blind allows the louvres to be drawn across the window led by the wand and adjusted into place by twisting the wand. If child safety is a particular issue the chain that links the bottom of the louvres together can be removed easily too by simply unclipping them.
If you have any questions around child safety and our blinds, please do not hesitate to get in touch, we're always happy to help.
Vertical Blind Technical Details
Our vertical blinds consist of an aluminium, white painted headrail, which hold the mechanism that drags the louvres back and forth and rotates them. The louvres are 89mm wide and have weights at the bottom to ensure they hang straight. The weights are connected by a plastic chain that is clipped to the weight.
Due to our unique method of manufacturing our vertical blinds, we’re unable to offer a ‘louvres only’ option, where customers buy just the louvres. This is because there is risk of compatibility issues with another brand of vertical blind and sizing may not match.
The ‘stack’ means when the louvres are at one end of the headrail. You have the option to choose whether the louvres can stack to the left, right or split, so they are stacked on the left and right side of the blind.
The size of the stack, with all louvres to one side of the blind, will be the below size:
A 1m wide vertical blind will have a stack size of 175mm. A 2m wide vertical blind will have a stack size of 305mm and a 3m wide blind will have a stack size of 435mm. Remember, if you choose a split stack option, this figure will be halved, with each half on each side.
You have the ability to tell us how you wish to fit your vertical blind when you come to order, which tells us which brackets to send with your blind. A top fix bracket is fitted to the top of the recess or to the ceiling and holds the headrail from above. A face fix bracket fits to the wall or above the window. A face fix bracket has the following dimensions: the footprint is 45mm x 31mm and the brackets projects 96mm x 20mm. You won’t need to account for these sizes when you measure as we take care of this based on the information provided when you order.
3 Year Warranty
A blind from DotcomBlinds is made to the highest standards, designed to provide you with years of service and shade.
In fact, we’re so confident and proud of our blinds, we offer a 3 year warranty on all our blinds. This is one of the longest warranties available and a clear sign of the quality of our blinds.
Obviously, there are a few exclusions:
✖ Damage caused by poor installation/not following fitting instructions (don’t worry, installation is easy, read this.)
✖ Misuse or Failing to maintain the blind
✖ General wear and tear and fading (these blinds are exposed to very intense UV rays)
✖ Alteration to the blind
✖ Exposure to the elements or fitted in an unsuitable location (these are indoor blinds!)
However, if your blind stops functioning for any reasons other than those listed above, get in touch. Our warranty covers:
✔ Manufacturing defects
✔ Fabric/slat colour fading within a year
✔ Mechanical malfunction
✔ 2 year warranty on battery motors used in electric roller blinds
So, in summary, avoid grossly mistreating your blind, show it a little TLC every so often and don’t use it in ways it wasn’t intended. If you do all those things and something goes wrong with the blind, you’re golden – we’ve got you covered and we’ll and repair or replace it free of charge.
Free Samples?Free samples are available on all of our fabrics and slats. Simply click the ‘order free sample’ button.
Your free sample will be added to the basket ready for you to checkout. You can carry on browsing, adding as many samples to your basket as you like. When you’re ready, checkout – delivery is free too – and relax, our samples will be on their way to you in no time.
Why order samples?We always recommend ordering samples to ensure you fall in love with the fabric or slat. Screen resolution and brightness settings vary and you may find some fabrics look a little different in real life to how they appear on a screen. You can hold a sample in your hands, feel the fabrics, the weave and see the opacity before your very eyes, something you can’t recreate online.
We’ve made every effort to accurately portray the fabric realistically, but you can never be too careful.
Quick TurnaroundWe pride ourselves on the speed with which we can get your free fabric samples to you. We send your samples with first class delivery to be with you the very next day. We often dispatch them the same day you place your order (and most certainly by the next working day if you order after hours or on the weekend). With our fast free fabric sample delivery you’ll be one step closer to shading your home with some of our fabulous blinds in no time at all!
Moisture resistant blinds do not absorb or retain water, meaning they will not rot when exposed to damp conditions. Ideal for kitchens and bathrooms.
Super easy to clean and perfect for busy households, simply wipe with a cloth to keep these blinds look spick-and-span!
A fire retardant blind will only smoulder when presented with a flame and will self-extinguish once the heat source has been removed. This can be added to your fabric by selecting this add-on at the checkout.
All our blinds come with child safe features as standard but some are inherently more child safe due to the deliberate removal of chains and cords.
This Blind is available for Next Day Delivery. Order before 11am to have it despatched the same day to be with you the very next working day. All you have to do is select ‘Next Day Delivery’ when you checkout and we’ll take care of the rest.
