33.7mm Tube Clamps FAQs

Are 33.7mm tube clamps the standard for handrail systems?

Yes – 33.7mm is one of the most common diameters for UK industrial handrail systems, meeting many standard safety and accessibility specifications. It provides a balance between strength and ease of handling, making it suitable for a wide range of applications.

Can these be used for both permanent and temporary installations?

Absolutely. The modular design and grub-screw fastening system mean they can be easily dismantled and reused, making them ideal for temporary site safety barriers, event crowd control, or exhibition frameworks, as well as fixed installations.

Do IMS supply the 33.7mm tube to match?

Yes – we stock galvanised steel tube in 33.7mm outer diameter, supplied in full lengths or cut to size. Sourcing both the clamps and tube from IMS ensures perfect compatibility and saves time on site.

What maintenance do 33.7mm tube clamps require?

Minimal maintenance is required. For safety-critical installations, it is recommended to periodically check grub screws for tightness and inspect clamps for any damage, corrosion, or wear – especially in high-traffic or exposed environments.

Can I mix 33.7mm clamps with other tube sizes?

Yes, but you will need the correct transition fittings or design adjustments to ensure structural integrity. Mixed-diameter systems are common where heavier sections are used for main runs and lighter sections for secondary rails or bracing.
