Sisäinen mastoliitin B-TECH SYSTEM 2 Ø50mm mastoille, teräs sinkitty, 30×40×200mm

B-Tech SYSTEM 2 internal pole joiner for Ø50mm poles is designed to extend the drop of System 2 installations. The joiner is manufactured from a single piece of 4 mm thick heavy-duty steel with a zinc finish and is sized to fit inside 50 mm diameter poles while allowing cables to pass through unimpeded.

Advantages

The one-piece 4 mm steel construction provides a rigid, seamless connection between poles, improving structural stability. Its internal fit preserves a clean external appearance and the central passage allows cables to run through the joined poles without obstruction. The zinc-coloured steel housing offers corrosion resistance appropriate for indoor and controlled-environment applications.

Suitable for

• Extending vertical pole runs in AV, retail or display System 2 installations
• Creating continuous internal cable pathways through joined Ø50mm poles
• Indoor and controlled-environment mounting where a discreet internal join is required

Key specifications

• Compatible pole diameter: Ø50 mm
• Material: Heavy-duty steel, single-piece construction
• Material thickness: 4 mm
• Finish / colour: Zinc
• Overall dimensions (approx.): width 30 mm × depth 40 mm × height 200 mm

How to use

Insert the joiner into the interior of aligned Ø50 mm poles and bolt through the poles to secure a rigid connection. Ensure cable routing is positioned through the central passage before final tightening to maintain an uninterrupted cable path. Tighten fasteners to the torque recommended by the System 2 installation guidelines to achieve a secure join.

Recommendations

Use the joiner as part of B-Tech System 2 assemblies and follow the manufacturer's installation instructions for load limits and fastener torque. Check compatibility with existing poles and confirm indoor or controlled-environment suitability based on the zinc finish.
