The house of clamps
Established in 1855, Herbert Terry & Sons had a long record of industrial achievement in the field of springs and industrial fasteners, where the Terry name became known and respected on a worldwide basis.
Tradition with Technology
The “Powergrip” range of hose clamps is manufactured to BS 5315 and has the British Standard Kitemark approval. Therobust "Powergrip" products gained their name owing to the high clamping force developed around the hose.
