NORRES CLAMP 210 BRIDGE CLAMP
Bridge clamp with plastic bridge for externally corrugated hoses
The NORRES CLAMP 210 BRIDGE CLAMP is a practical and cost-efficient bridge clamp designed for securing externally corrugated spiral hoses such as AIRDUC®, PROTAPE® and CP series. The plastic bridge ensures tight, uniform clamping without damaging the hose profile. The clamp is multi-piece, easy to fit, and reusable during maintenance or replacement.
Properties and construction
- Practically leak-proof and secure clamping by means of a specially designed plastic bridge.
- Quick and simple installation – reusable.
- Multi-piece design for flexible assembly.
- Materials: bridge made of PA6, clamp strip, screw and housing made of galvanised steel (W1).
- Complies with RoHS Directive and REACH Regulation.
Applications
For clamping externally corrugated hoses in extraction, ventilation, and material transport – e.g. NORRES AIRDUC®, PROTAPE®, and CP series.
Technical note
Bridge clamps with a plastic bridge, such as CLAMP 210, are ideal when a stable and vibration-resistant fastening is required without direct metal-to-metal contact. They are typically used for standard and antistatic hoses where equipotential bonding is not required. For ATEX installations, CLAMP 212 in stainless steel is recommended to ensure proper electrical conductivity.
Recommended accessories
- CONNECT 228 / 233 – adapter and coupling parts for AIRDUC® / PROTAPE®.
- CONNECT 270–271 – stainless/hygienic couplings for process and food industry applications.

FAQ: NORRES CLAMP 210 BRIDGE CLAMP
What is the NORRES CLAMP 210 BRIDGE CLAMP used for?
For fastening externally corrugated spiral hoses such as AIRDUC®, PROTAPE®, and CP series. The plastic bridge ensures even and tight clamping without damaging the hose.
How does it differ from the CLAMP 212?
CLAMP 210 features a plastic (PA6) bridge and galvanised steel parts, while CLAMP 212 is fully stainless and suitable for ATEX installations.
Can CLAMP 210 be used in ATEX areas?
No – the plastic bridge prevents full electrical contact. For ATEX zones, use CLAMP 212 or CLAMP 208 (W2/W4).
Which materials are used?
Bridge: PA6 (polyamide). Clamp strip, screw and housing: galvanised steel (W1).
How do I choose the correct size?
Determine the actual outer diameter of the hose and select a clamp whose clamping range covers that value. See the table below.
