The Award Winning Revolutionary Adjustable Spacer Fixing

The best products desire the best components and our ingenious fixing will streamline your manufacturing costs. Space-Plug is an award winning innovation business that has been supporting kitchen, bathroom and bedroom cabinetry manufacturers and installers for the best part of 10 years. To date Space-Plug has sold over 6 million of our fixings to kitchen, bathroom and bedroom cabinetry manufacturers around the world. Our unique patented product, saves both valuable time and money, when manufacturing and installing a cabinet base unit.

Our fixings are currently being used by thousands of kitchen cabinetry makers and installers all over the world. Affectionately known as the "kitchen fitters friend". Our adjustable spacer fixing, reduces the amount of materials used to manufactuer kitchen units (or any other type of base unit) and by reducing the weight of each unit, this reduces shipping and packaging costs. Kitchen installers embrace the time saved using them and also they create less waste as the units fabrication isn't compromised to accomodate pipes and cables.

Our fixings are
manufactured in the UK.

All the tooling to make our products is based in the UK, on the South Coast of England to be precise. We are not reliant on the manufacture of our products overseas. We are agile and flexible to accomodate any sized order within a short turnaround.

Wren Kitchens provide our fixings in the box for their customers. You can read about why they chose to work with us in our case study.

And please remember, it usually takes just ONE adjustable spacer fixing to securely fix ONE base cabinet to a wall. A huge reduction on the amount of components used compared with traditional fixing methods.

Let's introduce you to our Adjustable Spacer Fixing >>>

Space Plug

There are currently TWO ways to use
our Adjustable Spacer Fixing (with a 3rd in production!).

1. With Sides

Kitchen base units require a service void to accommodate pipework. Whether your base units voids are 30mm or 70mm in depth the adjustable spacer fixing bridges the gap up to 80mm.

For the kitchen installer or home DIYer, there is no more working in tight spaces at awkward angles - they can just work straight on. With our adjustable spacer fixing they have the entire cross-brace for fixing. Easy to avoid pipework or even to line up with wall studs to avoid dreaded cavity wall fixings. It provides the kitchen installer complete freedom to fit as required.


They can even standoff further than the depths of the sides to accommodate deeper worktops.

Our adjustable spacer fixing is accurate, there is no need to mark, just simply fix whilst the base unit is in place exactly where you want to. Wren Kitchens took one look at our product and said "That's a no brainer". Wren Kitchens sell their base unit's with our adjustable spacer fixing in the box. Please read our case study for more information.

2. No Sides

Our adjustable spacer fixing also can be used on cabinetry manufactured with no sides. This might not be a concept that as a manufacturer you have considered. Probably because up until now there was no alternative. However, there are custom kitchen cabinet makers in the UK that have adopted the idea that we have called AFS - Advanced Fixing System. Chris Sharp Cabinets is one such cabinet maker that uses AFS and here is why;

  • Save money by saving material. Most base units can be reduced by at least 50mm x 720mm x 2.
  • Save money by reducing waste. Cutting smaller parts results in increased optimisation.
  • Save money by reducing hardware. L Brackets, fixing screws, access holes and cover caps can all go.
  • Save money with a smaller product. Whether flat-pack or rigid, smaller boxes means more room in the warehouse, more room on the lorry and less packaging.

Your manufacturing process has less impact on the planet. If every kitchen manufacturer in the UK moved to Space-Plug ASF there would be enough board saved EVERY YEAR to lay a path of 8x4's from London to Paris.

Removing the service void sides to your base cabinets is great for your bottom line, great for the customer, and great for the environment.

Don't just take our
word for it!

We meet a lot of kitchen installers, many may install your kitchens and they are all impressed by our adjustable spacer fixing. We compiled a short video when we went on tour in the summer of 2019.

Large Space Plug

I’m a professional kitchen fitter and happened to see these plugs advertised on a forum, I liked the look of them and decided to give them a’s my thoughts. This product is suitable for both professionals and DIYers. The initial thing I like about it is that when you’ve prepped your base cabinet and drop them into position you don’t have to move them again. The traditional method of fitting is to place the cabinet, mark your holes where the brackets go, remove cabinet to drill holes and fit pugs, replace cabinet and recheck all levels and then fasten, this is all a thing of the past with this product...Just place your cabinet, check your levels, fit Space Plug and that’s it...finished. Move on, save time, save money and make life easy. It’s made from a sturdy heavy duty plastic and is easy to adjust. If you’re a pro then I would recommend because it saves money with the time element, if you’re a DIYer I would recommend because it’s just gonna make your life easier. Overall a fantastic idea at an affordable price....would highly recommend.

Why have I not discovered these before!

What a simple yet time saving device, gone are the days of making a shim to install something to a firm backing. I needed to secure a bracket to a wall that is Plasterboard dot and dab, using these made this possible and not just that made it quick and easy. I cut a 32mm hole in the plasterboard and placed the spacer against the brick wall behind, then using the extra long drill bit (provided) drilled out and hey presto. Just need to ensure you have some long screws to hand and your golden. Will be ensuring I always have a pack of these in my kit back from now on.

Purchased direct from our website

I'm a DIY'er and will be using the space plug to help secure some built-in storage I am making to the walls / ceiling. It will be really useful for what I need so thanks. I'm an industrial designer for my day job. I design and develop products for a living. Just have to say I love seeing people coming up with good ideas and then even more so when they take it successfully to market off their own back. Well done, looks like you have done a great job and created a genuinely useful product here 👍


Game Changer

Been using these for coming up to about 2 years now and very rarely use anything else to fix kitchen units (also found tons of other uses for them). At first I was skeptical about the product, I mean did I really need them? But then the second you try them everything clicks in place and you just 'get it'. One of the huge benefits is when fixing to stud walls as you can place the fixing anywhere you like along the back rail of the kitchen unit and so can always fix to a stud. That really is a game changer and I can't express enough how much time is saved. To be honest I wasn't buying these from screwxfix before but it seems SF have dropped the price of these and are now one of the cheapest places to purchase them. So will be getting all my future orders. Just try them and although they are sold as kitchen unit fixings, you'll so find yourself using them for all sorts. Really handy to have in the tool bag to get you out of trouble.

What amazing products for levelling a shower tray

I searched for small and micro-adjustable raisers that could level out a shower tray. Space Plugs offered a perfect fix. These are available in 2 sizes. The newly tiled floor in our old cottage has a slope that advocated raising the front part of the stone shower tray, and I did not want to just chuck under pieces of wood. Space Plugs are the perfect fix to this problem - they can be micro adjusted to achieve a perfect level - Utterly Brilliant! Huge thanks to the UK inventor Cliff and his brother for inventing, developing and marketing and distributing these wonderful devices.
