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 👍


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.

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.
