Why Choose the ABB Long Bolted Bracket (290mm)?
The ABB Long Bolted Bracket (290mm) is a dedicated wall-fixing accessory for external lightning protection systems, designed for bolted fixing of an offset lightning protection mast to a vertical wall. It forms part of ABB's external lightning protection accessory range and provides a robust mechanical mounting solution for lightning rods and their supporting mast assemblies.
The bracket provides a 290 mm offset, allowing the lightning protection mast to be positioned away from the mounting surface where additional clearance is required. It is suitable for masts with diameters from 30 to 50 mm and uses M10 bolted fixing, with Ø11 mm bolt holes positioned 120 mm apart.
Identified by ABB type B752155, the Long Bolted Bracket is supplied individually and has a unit weight of 1.50 kg in ABB's current external lightning protection catalogue. ABB specifies a minimum of two brackets for fixing lightning rods, with three fixing brackets required for lightning rods installed on mast assemblies reaching 5 to 6 m. The product is supplied under ABB order code 2CTH050016R0000.
Key Advantages
- Purpose-designed for bolted fixing of an offset lightning protection mast to a vertical wall.

Secure Offset Wall Mounting for Lightning Protection Masts
Correct mechanical support is an essential part of an external lightning protection installation. The ABB Long Bolted Bracket creates a 290 mm offset between a compatible 30–50 mm diameter mast and the vertical wall, making it particularly useful where greater clearance from façades, roof edges or other structural features is required.
ABB specifies at least two bolted brackets when fixing lightning rods. Where a lightning rod is installed on a mast assembly reaching 5 to 6 m, three fixing brackets are required. Bracket quantity, mast configuration, fixing method and structural suitability should always be considered as part of the complete external lightning protection system design.
Typical Applications
- Wall mounting of external lightning protection masts.
- ABB OPR lightning protection installations.
- Lightning rod and air-terminal mast support.
- Commercial building lightning protection systems.
- Industrial facilities and manufacturing sites.
- Warehouses and logistics facilities.
- Infrastructure and utility installations.
- External lightning protection systems requiring a 290 mm mast offset.
