Pipe clamp Niczuk Obejma DUO 4 BK (106–113) for 4-inch pipes, diameter range 106–113 mm

Niczuk Obejma DUO 4 BK (106–113) is a pipe clamp designed for mounting and securing 4-inch pipes with an outer diameter of 106–113 mm. The clamp provides mechanical fixation for ventilation, drainage and exhaust pipelines, allowing reliable support whether mounted on walls or ceilings. Constructed to hold pipes firmly in place, it facilitates accurate alignment and connection during HVAC and plumbing tasks.

Advantages

The DUO 4 BK clamp combines a compact profile with robust holding capability, enabling straightforward installation and long-term stability of mounted pipes. Its adjustable diameter range covers common 4-inch duct sizes, reducing the need for custom fittings. The design allows mounting to various surfaces and helps prevent pipe movement and vibration transmission.

Suitable for

• Mounting and securing ventilation ducts with outer diameter 106–113 mm
• Fixing drainage and exhaust pipes of matching size
• Wall or ceiling installations in residential and commercial HVAC systems
• Temporary or permanent mechanical support during pipe alignment and connection

Key specifications

• Pipe outer diameter range: 106–113 mm
• Intended pipe nominal size: 4 inches
• Mounting locations: wall or ceiling
• Function: mechanical clamp for pipe support and fixation
• Typical applications: ventilation, drainage, exhaust systems

How to use

Position the clamp around the pipe so the pipe outer diameter lies within the 106–113 mm range. Secure the clamp to the chosen mounting surface using appropriate fasteners for the substrate (screws, anchors, or bolts), ensuring the clamp is tightened sufficiently to prevent pipe movement without deforming the pipe. Align adjacent pipe sections before final tightening to maintain airtight or watertight connections as required for the intended system.

Usage recommendations

Use corrosion-resistant fasteners and choose anchors suitable for the wall or ceiling material. Verify that the clamp's diameter range matches the actual pipe outer diameter and avoid over-tightening which could damage thin-walled ducts.
