SRH is a carrying handle which makes it substantially easier to manually move circular ventilation ducts at the building site.
The handle fit ducts Ø 315–1250, but it is adequate to limit its use to the sizes Ø 400–800. You ought not to exceed the recommended maximum carrying weight of 25 kg per person.
One person at each duct end uses a handle each.
