CLAMP 211
CLAMP 211 is a T-bolt clamp developed for heavy-duty hoses with a smooth outer wall. The characteristic T-bolt construction provides quick mounting without special tools and allows the clamp to be reused multiple times without losing clamping force. The clamp is supplied in 34 dimensions with a clamping range from 17 mm to 280 mm, so every hose diameter in the AIRDUC PUR/PVC and PROTAPE series can be paired with a suitable clamp. Typically used in industrial installations where the hose periodically must be detached - e.g. for cleaning, reconfiguration or servicing of pneumatic conveying lines.

Frequently asked questions
Which hoses fit CLAMP 211?
CLAMP 211 is a T-bolt clamp designed for heavy-duty hoses with a smooth outer wall. The clamp is qualified for our AIRDUC PUR/PVC series, PROTAPE series and similar hoses with an even outer wall. For strongly corrugated hoses we recommend CLAMP 216 instead. Always verify compatibility by measuring the hose's outer diameter and choosing a clamp where the measurement falls within the clamp's clamping range (min-max).
What is the clamp material?
Producentens factsheet for CLAMP 211 does not explicitly state the body material. T-bolt clamps in this series are typically available in multiple surface variants (standard SKU 2110000 plus variants 2119200 and 2119230 with different surface treatments). Always confirm exact material specifications when ordering - we contact the manufacturer for documentation if your project has specific requirements for steel grade or corrosion resistance.
Why are there 34 different sizes?
T-bolt clamps have a relatively narrow clamping range (typically 2-5 mm span between min and max) to ensure precise mounting without damaging the hose. The 34 sizes cover from 17 mm to 280 mm hose diameter with sufficient overlap that any dimension in the hose catalogue can be paired with a suitable clamp. Choose the clamp where the hose's actual outer diameter falls within the clamp's clamping range - not at the very edge.
Can the clamp be reused?
Yes. CLAMP 211 is specified as reusable in the factsheet. The T-bolt construction allows the clamp to be opened and closed multiple times without losing clamping force. This is a significant advantage compared to single-use clamps in installations where the hose periodically must be detached - e.g. for cleaning or servicing.
Are clamps sold individually?
Yes. Each dimension has its own article number, and clamps are sold per piece. For pre-assembled hose sets with clamps on both ends, we advise on dimension configuration based on the hose's precise outer diameter - send us a specification and we'll assemble.
