## Long description

Duct clamp with cladding Niczuk 81210250000 (500 BK) is a metal fastening device designed to secure circular ventilation ducts with a 500 mm external diameter. The product combines a mechanical clamp and an outer cladding that covers the joint, providing a neat finish and additional protection against dust and mechanical damage. It is intended for use in HVAC installations where a covered connection and stable support of duct runs are required.
Advantages
The clamp integrates a robust fastening band with a fitted external cladding that conceals the connection and reduces the risk of snagging or exposure. Constructed from corrosion-resistant coated metal, it offers dimensional stability and reliable holding power for large-diameter ducts. The cladding improves appearance and helps protect the joint from impacts, dust accumulation, and minor moisture ingress without affecting airflow.
Suitable for
Securing circular ventilation ducts with a 500 mm diameter
HVAC installations in residential buildings
Commercial ventilation systems and light-industrial ducting
Situations requiring a covered, tidy duct joint and stable mechanical support
Key specifications
Designed for circular ducts with nominal diameter 500 mm
Integrated external cladding for joint coverage and protection
Metal construction with protective coating to resist corrosion
Mechanical fastening suitable for wall, ceiling or hanger supports
Suitable for indoor HVAC applications in dry or mildly humid environments
How to use
Position the clamp around the duct joint so the edges of the two duct sections align evenly. Close and tighten the fastening band to achieve a secure, even grip without deforming the duct. Ensure the external cladding is seated over the joint and engages correctly with the clamp profile. Mount the assembly to the supporting structure using appropriate anchors or hangers rated for the duct weight and installation conditions. After installation, inspect the joint and cladding for alignment and tightness.
Usage recommendations
For optimal long-term performance, use compatible anchors and supports sized for the weight and length of the duct run, avoid overtightening the clamp to prevent deformation of the duct, and perform periodic inspections in areas subject to temperature or humidity fluctuations.
