## Summary description

Ventilation clamp by Niczuk designed for securing ducts and pipes with a 450 mm lining. Provides a fixed mounting point for ventilation systems, helping to stabilize and seal connections.

## Long description

The Niczuk ventilation clamp with 450 mm lining, model 81210245000, is a lined duct clamp designed to secure circular ventilation ducts and pipes. It provides a fixed mounting point that stabilizes duct runs, protects duct surfaces from damage with its 450 mm lining and helps reduce vibration transfer. The clamp is suitable for use in residential and commercial HVAC installations where a lined clamp is required to maintain duct integrity and consistent sealing.
Advantages
This lined clamp protects duct surfaces from abrasion and deformation, extending the service life of ventilation ducts. The 450 mm lining ensures an even contact area around the duct, improving load distribution and sealing performance. Its construction reduces vibration transmission, contributing to quieter operation of ventilation systems. The clamp is designed for straightforward installation and provides a reliable anchor point for hangers and supports.
Suitable for
Securing circular metal or insulated ventilation ducts
HVAC installations in residential buildings
Commercial ventilation systems requiring lined supports
Areas where vibration isolation and surface protection are important
Key specifications
Lined clamp for ducts with 450 mm lining width
Designed for circular duct profiles commonly used in ventilation systems
Provides surface protection to prevent abrasion and deformation
Reduces vibration transmission between duct and support
Suitable for indoor HVAC installations in residential and commercial settings
How to use
Select a mounting location that provides adequate support for the duct run and aligns with existing hangers or building structure. Position the lined clamp around the duct so the lining contacts the duct surface evenly. Secure the clamp using appropriate fasteners compatible with the mounting substrate, ensuring the clamp holds the duct firmly without over-tightening and compressing the lining excessively. Adjust the clamp and any associated hangers to achieve the correct duct slope and alignment before final tightening.
Usage recommendations
Use corrosion-resistant fasteners appropriate to the installation environment and follow local HVAC installation standards. Inspect the lining periodically for wear or compression and replace the clamp if the lining no longer provides effective protection. Avoid over-tightening to prevent damage to insulated ducts and ensure vibration-reduction benefits are maintained.
