Description

The BR-48 blind rivet is the standard fastener for permanent duct assembly where a flush, tamper-resistant joint is required. The aluminium body with a steel mandrel provides a strong, vibration-proof connection through pre-drilled holes, with a dome head that sits neatly on the duct surface. Blind rivets are preferred over screws in applications where the internal duct surface must remain smooth to minimise airflow resistance and prevent lint or grease accumulation.
