At the Key Clamp Store, we’ve designed our product codes to make it as simple as possible for you to find the right fitting for your project. Each code follows a consistent two-part format that identifies what type of fitting it is and which tube size it fits.
This means you can quickly understand a code at a glance and easily match fittings with your required steel tube diameter.

The basis behind this is simple.
We get asked a lot whether, if given a specification or set of drawings, we can turn this into a quote. This is our speciality!
We aim to get quotes done same day during business hours. We can include everything that the job requires, we can supply this cut to size, and we can supply quotes for powdercoating and painting if necessary.
We often get asked the question - what size is best for clothing rails. As key clamp becomes more popular, we would like to share our thoughts on the size required, and why we think that this is the best choice.
3 of the Key Clamp Sizes, 27mm, 34mm and 42mm will take a coathanger, but 42mm - only just! Most coathangers will just squeeze on to 42mm tubing - this means its hard to slide clothes back and forth, and, premature wearing of the galvanised coating on the tubing. In short - 42mm isnt a wise choice.
27mm tends to be used extensively for in-home projects, and does work under most circumstances, however, it can look a bit 'weedy' when its holding up several items of clothing. The items tend to mute the industrial style of the rail (which is the whole point, right?) and doesnt show up so well.
34mm tubing is perfect. Hangers
