Pipe Clamp Niczuk Obejma DUO 150 BK adjustable 149–157 mm

Niczuk Obejma DUO 150 BK adjustable 149–157 mm is a pipe clamp engineered to secure circular pipes and ventilation ducts with an effective diameter range of 149–157 mm. Manufactured for indoor and technical assembly use, the clamp features an adjustable band and fastening points that allow stable fixation of round conduits in HVAC, plumbing and ventilation systems. The product is intended to provide a compact, reliable mounting solution where precise pipe centring and vibration reduction are required.

Advantages

The adjustable design accommodates slight variations in pipe diameter within the specified range, reducing the need for multiple fixed-size clamps. Constructed from materials suited for indoor installation, the clamp offers consistent clamping force and alignment while facilitating straightforward mechanical fixing. Its compact profile helps save space in crowded installation zones and supports standard fastening methods used in technical and building services work.

Suitable for

• Securing circular HVAC ducts and ventilation pipes
• Mounting plumbing conduits and waste pipes in indoor installations
• Fixing round conduits that require vibration damping and stable alignment
• Technical rooms and building services where adjustable pipe support is needed

Key specifications

• Adjustable diameter range: 149–157 mm
• Clamp type: adjustable band clamp for round pipes
• Intended use: indoor and technical assembly
• Application areas: HVAC, ventilation, plumbing
• Profile: compact design for space-efficient mounting

How to use

Select the clamp and position it around the pipe so the band fully encircles the conduit at the intended fixing point. Tighten the adjustment mechanism until the clamp provides firm, even contact without deforming the pipe. Attach the clamp to the supporting structure using appropriate mechanical fasteners compatible with the mounting surface. Verify alignment and make incremental adjustments to ensure the pipe remains centered and secure.

Usage recommendations

Use the clamp within the specified diameter range of 149–157 mm and choose corrosion-resistant fasteners for humid environments. Avoid over-tightening to prevent deformation of thin-walled ducts. For vibration-prone installations, combine the clamp with suitable damping pads or isolation mounts.
