Yes, in many cases, you can use the same brackets for different types of cables, but it's not always the best idea.  

Compatibility depends on the size, weight, bend radius, and installation environment of the cables you're working with. Think of cable brackets as the Swiss Army knife of the cable world, only effective when used correctly. 

Using a one size fits all approach can lead to poorly supported cabling, which risks signal interference, damage, or even non-compliance with electrical standards. So, before you start clipping everything in place with a single bracket type, let’s dig into what you should really be considering. 
 

Why it matters 

Different cables have different requirements. A data cable doesn’t behave like a thick power cable, and neither should be treated the same when it comes to support. Brackets designed for Cat6 may not offer adequate grip or spacing for fibre, coax, or twin and earth. 

Considerations when choosing brackets 

Cable type and diameter 

Always match bracket size to cable diameter. A bracket that’s too tight can crush the cable; too loose, and it won’t stay in place. 

Weight load 

Power cables or bundles of heavy duty wiring need brackets that can bear the load over time, especially when mounted in ceilings or high traffic areas. 

Bend radius 

Cables like fibre optic need more gentle curves to avoid signal loss. Avoid sharp bends by using brackets that allow enough space and flexibility. 

Installation environment 

Are you routing cables in ceiling voids or wall cavities? In damp or dusty environments? Go for brackets with corrosion resistance or extra grip where needed. 

 

Smart cable routing tips 

Spacing matters 

Don’t just fix brackets wherever feels convenient. Stick to recommended bracket spacing for cables, usually every 300mm for horizontal runs and 400–500mm for vertical ones. 

Ceiling voids and tight spaces 

In awkward areas, use mini trunking or adaptable clips that help route cables neatly without over bending them. Look for options that allow re-entry so you can make future tweaks without ripping everything out. 

Avoid overcrowding 

Stacking power and data cables in the same bracket is a recipe for interference. Keep them separated using individual brackets or dedicated pathways. 

Let’s say you’re running Cat6 and coax cables through a ceiling void. While both are low voltage, they vary in size and shielding. Using a single, universal bracket may seem efficient, but it could pinch the coax or let the Cat6 sag. Opt instead for multi-way brackets or clip sets that keep each cable properly supported. 

On the flip side, if you’re installing several 2.5mm twin and earth cables along a stud wall, a heavy-duty bracket or clip rail that supports multiple parallel runs could work perfectly. 

FAQs 

Can I secure power and data cables in the same bracket? 

Not recommended. Electrical regulations advise keeping them separate to prevent interference and maintain signal integrity. 

How do I know what size bracket to use? 

Measure the outer diameter of the cable and choose a bracket that offers a snug, but not tight, fit. Some manufacturers provide sizing guides for specific cable types. 

What’s the best way to fix cable brackets to walls? 

Use wall plugs and appropriate screws if you're mounting into masonry. For stud walls, find the timber or use suitable plasterboard fixings. 

Can I use adhesive-backed clips in ceiling voids? 

They’re fine for temporary or light-duty use, but in warm or dusty voids, adhesive can fail. Opt for screw fixed brackets for a long-lasting hold. 

Are there brackets for mixed cable sizes? 

Yes, some mounting systems allow for custom combinations, ideal for routing different cable types along the same path while keeping them separate. 
 

 

Final thoughts 

Using the same brackets across multiple cable types isn’t always the cable management shortcut it appears to be.  

With the right bracket choices, you'll not only secure your cables properly but also make your installation cleaner, safer, and compliant.  

So next time you’re knee deep in cable clips and ceiling dust, remember, one bracket doesn’t always rule them all.
