Single Bossed Clamps – Heavy-Duty, with DÄMMGULAST® Red (Galvanised) 33481

High-Temperature • Fire-Protected • Heavy-Duty Galvanised Clamp

Single Bossed Clamps – Heavy-Duty, with DÄMMGULAST® Red (Galvanised) 33481 are robust, high-performance pipe supports engineered for heavy-duty industrial, HVAC, and mechanical installations. Constructed from corrosion-resistant galvanised steel with an increased material cross-section and reinforced fastening latches, these clamps ensure maximum structural strength and long-term reliability under dynamic or thermal stress.

Featuring the DÄMMGULAST® Red vibration control lining, the clamp delivers exceptional acoustic and vibration damping performance, achieving an average sound reduction of up to 24 dB(A). The lining is designed for high-temperature resistance up to +200°C, making it ideal for hot water, steam, and thermal oil applications. Certified for fire protection and VdS-approved for sprinkler system use, this clamp meets the highest safety and performance standards in its class.
