Why Choose the nVent HOFFMAN S1MTBB Rotary Base Bracket?
The nVent HOFFMAN S1MTBB is a robust rotary base bracket designed for the nVent HOFFMAN light-duty HMI suspension system. It provides the mounting point between a suspension arm and a horizontal surface while allowing the entire attached suspension system to rotate, making it ideal for industrial operator-interface installations that require flexible positioning.
The S1MTBB allows the suspension arm to rotate through 300 degrees at the mounting point. An integrated safety stop helps control the available movement, while maintenance-free bearings provide smooth and dependable rotation. Its die-cast aluminium construction combines mechanical strength with relatively low weight for demanding industrial machine and automation applications.
Measuring 166 mm high × 128 mm deep and weighing approximately 1.70 kg, the S1MTBB is finished in RAL 9005 black. It is supplied with installation instructions, gaskets and tube setscrews for integration with compatible suspension components; surface mounting hardware is not included.

Flexible Mounting for Industrial HMI Systems
Rotary base brackets provide a flexible mounting point for industrial HMI suspension systems by allowing the complete arm assembly to move around its attachment point. The nVent HOFFMAN S1MTBB mounts on a horizontal surface and provides 300-degree rotation, enabling operators to reposition an attached HMI enclosure or control panel to suit different working positions around machinery.
The combination of die-cast aluminium construction, maintenance-free bearings and an integrated safety stop makes the S1MTBB suitable for machine-building and industrial automation applications where operator interfaces need to be repositioned regularly. Used with compatible nVent HOFFMAN light-duty suspension profiles and couplings, it forms a configurable support system for suspended control equipment.
Typical Applications
- Industrial HMI and operator-interface suspension systems.
- Rotatable machine control panels and operator stations.
- Manufacturing and production machinery.
- Automation and process-control installations.
- Suspended electrical and control enclosures.
- OEM machine-building and customised HMI installations.
