Single Bossed Clamps – Heavy-Duty, with DÄMMGULAST® Yellow (Galvanised) 33480

Heavy-Duty • Fire-Protected • Vibration-Controlled Galvanised Clamp

Single Bossed Clamps – Heavy-Duty, with DÄMMGULAST® Yellow (Galvanised) 33480 are industrial-grade pipe supports engineered for high-load applications in HVAC, sanitary, and industrial systems. Built from heavy-duty galvanised steel, these clamps feature a reinforced cross-section and robust tightening bolts, providing exceptional stability and strength for pipelines exposed to dynamic loads and thermal expansion.

Incorporating DÄMMGULAST® vibration control lining with a distinctive yellow identification stripe, these clamps deliver superior acoustic and vibration damping — reducing structure-borne noise by up to 22 dB(A). Fire-protection certified and compliant with DIN 3567 standards, they ensure safe, long-lasting, and quiet operation in demanding indoor environments.
