MiniRail 100mm

Mini Rail System variants

100 mm Roof Clearance

MiniRail 100mm

Standard 100 mm clearance — optimal ventilation for residential & light commercial projects.

The MiniRail 100mm delivers 100 mm of roof clearance in a compact 68 mm profile height. Landscape panel orientation maximises row width on narrower roofs. Z-clamp and end-clamp attachment accommodates all standard panel frame thicknesses without additional tooling. Rivet-and-EPDM tape base fixing preserves the roof membrane.

100 mm clearance — excellent ventilation
Compact 68 mm profile — minimal visual impact
Landscape orientation for wider rows
Z-clamp & end-clamp panel attachment
Minimal raw material usage — cost-effective
Compatible with all PV module brands

Applications: Residential rooftop · Light commercial · Warehouse · Industrial shed

Roof Clearance	100 mm
Panel Thickness	30 mm · 35 mm · 40 mm
Material	Aluminium 6063 T6 · SS 304 · EPDM
Design Wind Speed	Up to 200 km/h
Orientation	Landscape
Attachment	Rivet + EPDM tape
Finish	Anodized / Non-anodized

70 mm Roof Clearance

MiniRail 70mm

Compact 70 mm clearance — lower profile for wind-sensitive or aesthetically driven projects.

The MiniRail 70mm reduces the mounting height to 70 mm, creating an even lower profile that blends with the roof line. Ideal for sites with strict visual guidelines or higher wind-load requirements. Panel attachment and material specifications are identical to the 100 mm variant. Its cost-efficiency makes it a frequent choice for residential developments.

70 mm clearance — near-flush roof profile
Low visual impact — aesthetics-driven projects
Reduced wind moment vs 100 mm variant
Landscape orientation — wider row coverage
Most cost-effective in the Mini Rail range
Compatible with all PV module brands

Applications: Residential rooftop · Aesthetics-sensitive site · High wind zone · Light commercial

MiniRail 70mm specifications
Profile Height	68 mm
Roof Clearance	70 mm
Panel Thickness	30 mm · 35 mm · 40 mm
Material	Aluminium 6063 T6 · SS 304 · EPDM
Design Wind Speed	Up to 200 km/h
Orientation	Landscape
Attachment	Rivet + EPDM tape
Finish	Anodized / Non-anodized

Compact Span · Portrait

Short Rail

Compact short-span rail for narrow bays, canopies and retrofits — same T-slot, all SunMount clamps compatible.

The Short Rail is a compact aluminium extrusion for rooftops where a full-length rail is impractical due to narrow bay widths, limited purlin spans or modular roof layouts. Its reduced length minimises material usage and simplifies logistics while keeping the same T-slot profile that accepts every SunMount U-clamp, Z-clamp and mid-clamp. Ideal for canopies, carports and residential retrofits.

Short span — designed for narrow-bay rooftops
Reduced material & logistics cost
Same T-slot — all SunMount clamps compatible
Modular — cut to exact bay width on site
Fast installation on compact or retrofit projects
Compatible with all PV module brands

Applications: Compact residential · Canopy / carport · Narrow-bay industrial · Retrofit installation

Short Rail specifications
Profile Length	Short-span (custom cut)
Profile Height	68 mm
Panel Thickness	30 mm · 35 mm · 40 mm
Material	Aluminium 6063 T6 · SS 304 · EPDM
Design Wind Speed	Up to 200 km/h
Orientation	Portrait
Attachment	Rivet + EPDM tape
Finish	Anodized / Non-anodized
