Ventilation Clamp Niczuk 560 BK with lining

Ventilation Clamp Niczuk 560 BK with lining is a metal fastening band designed to secure round ducting and HVAC components with a nominal diameter of 560 mm. The integrated lining provides improved sealing between the clamp and the duct surface while protecting the duct finish from direct metal contact. The clamp is suitable for use in residential and commercial ventilation systems where stable mechanical support and reduced vibration transfer are required.

Advantages

The Niczuk 560 BK clamp features an internal lining that enhances sealing and prevents abrasion of duct surfaces, contributing to longer service life of installed ventilation components. Its design ensures even clamping pressure around the duct circumference for reliable fixation and reduced air leakage. Constructed from corrosion-resistant metal with a black finish, the clamp provides consistent mechanical performance and a discreet appearance in visible installations.

Suitable for

• Securing round metal or coated ventilation ducts with nominal diameter 560 mm
• Mounting and stabilizing duct sections in residential HVAC systems
• Commercial ventilation installations where lined clamps are required to protect duct surfaces
• Applications requiring reduced vibration transmission and improved sealing at clamp points

Key specifications

• Nominal diameter: 560 mm
• Material: corrosion-resistant metal band with protective finish
• Internal lining: integrated sealing/protective layer
• Finish/color: black
• Intended use: fastening and stabilization of round ventilation ducts

How to use

Position the Niczuk 560 BK clamp around the duct or component so the lining contacts the duct surface evenly. Align the clamp ends and tighten the fastening mechanism according to the manufacturer's recommended torque to ensure uniform compression of the lining without deforming the duct. Verify that the clamp sits squarely around the circumference and that the lining provides continuous contact to reduce air leakage. For repeated installations, inspect the lining for wear and replace the clamp if the protective layer is damaged.

Usage recommendations

Use the clamp in combinations with appropriate support brackets or hangers to distribute load and avoid point stress on the duct. Avoid overtightening to prevent deformation of thin-walled ducts; follow local building codes and HVAC installation standards for spacing and fixing of duct supports.
