FISCHER Thermax 12/110 M12 Stand-off Mounting System, 2 Pieces

On a coastal renovation, a crew mounts balcony railings onto a wall with thick external insulation. Salt-laden air and thermal bridging are constant threats. The FISCHER Thermax 12/110 M12 stand-off mounting system answers both: a thermally broken anchor with a stainless steel A4 rod and a fiberglass-reinforced nylon cone that keeps the fixing secure without compromising the building envelope.

Key specifications

• Stand-off distance: 110 mm
• Thread size: M12
• Drill hole diameter: 20 mm
• Minimum drill hole depth: 170 mm
• Overall anchor length: 170 mm
• Threaded rod material: Stainless steel A4 (V4A)
• Cone material: Fiberglass-reinforced nylon
• Pack contents: 2 complete sets including fischer FIS V injection mortar
• Thermal bridge value: Low (thanks to plastic cone)
• Temperature resistance: -40°C to +80°C
• ETA approval: ETA-12/0070

Why choose it

The Thermax system minimizes thermal bridging through its plastic cone, which separates the threaded rod from the substrate, reducing heat loss and condensation risk. The stainless steel A4 rod offers outstanding corrosion resistance, making it ideal for coastal and industrial environments. Combined, these materials deliver high load capacities while maintaining a compact footprint. The included FIS V mortar ensures a reliable chemical bond even in masonry, and the set comes with two complete assemblies for a two-point fixing task.

Ideal use cases

• External Thermal Insulation Composite Systems (ETICS)
• Mounting brackets, railings, canopies, and heavy facades
• Coastal and industrial environments requiring high corrosion resistance
• Renovation projects with thick insulation layers

Good to know

Installation requires drilling a 20 mm hole to a depth of at least 170 mm, injecting the FIS V mortar, and setting the anchor. The system is suitable for concrete, solid brick, perforated brick, and aerated concrete. Always follow the ETA guidelines for load calculations and edge distances.
