Secure, repeatable joins - with EN74 and BS1139 testing
Manufacture and testing to EN74 (or BS1139) means clamps are produced to established mechanical tolerances, with every batch tested to the latest regulations. Test certificates are available on request for compliance checks.
Consistent clamp strength reduces the risk of loose joints on site, giving confidence during erection and dismantling. Contractors can rely on predictable performance across multiple jobs.
Corrosion resistance for outdoor use - with zinc coating and passivation
Zinc coating followed by passivation forms a protective layer that slows surface oxidation and limits rust formation in exposed conditions.
Reduced corrosion lowers maintenance and replacement frequency, keeping scaffold assemblies serviceable for longer. Less downtime is needed for part swaps in wet or coastal environments.
Accurate fit for standard tubes - with 48.3mm diameter design
Components are sized specifically for standard 48.3mm scaffold tubes to ensure correct seating and clamping geometry.
Faster assembly and secure alignment make on-site work smoother, with users reporting a perfect pole fit and reliable performance during repeated use.
