The Fastensol Triangle Bracket (MPTB-GS) is a fixed-angle mounting bracket designed for solar PV installations on flat roofs and ground-mounted arrays where panels are fitted in portrait orientation. It tilts the array to a fixed 30 degree angle, giving reliable rainwater run-off and improved energy yield compared to a flat-laid panel, and is a cost-effective alternative to proprietary triangle systems such as Trisole.
Built from 40x40mm L-profile aluminium rail, the bracket is supplied in three lengths — 1410mm, 1350mm, and 720mm — that combine to form the rigid triangular support structure. It can be fixed to a metal roof deck using tapping screws or hanger bolts, or to a flat roof or ground base using expansion bolts, and is compatible with both Fastensol H-profile rail and standard Fastensol mounting rail.

Please Note: This listing is for the bracket only. It does not include screws, hanger bolts, or cross-connect clamps — these must be selected separately depending on the fixing method and rail system being used with the bracket.
30 Degree Fixed Tilt
Sets the module array to a 30 degree tilt angle, improving energy yield over flat-mounted panels while maintaining a stable, low-profile structure suitable for flat roofs and ground mounts.
Aluminium & Stainless Construction
System components are manufactured from high quality aluminium and stainless steel, giving strong corrosion resistance for long-term outdoor use.
Three-Piece Rail Design
Supplied as three rail lengths — 1410mm, 1350mm, and 720mm — in 40x40mm L-profile, which assemble into the triangular bracket frame.
Flexible Fixing Options
Can be fixed using tapping screws or hanger bolts on metal roofs, or expansion bolts on flat roofs and ground mounts, depending on the substrate.
Compatible Rail Systems
Works with Fastensol H-profile rail via rail bolts, or with standard Fastensol rail via cross-rail brackets and hex nuts, giving flexibility across installation types.
Wide Slope & Wind Rating
Rated for roof slopes of up to 60 degrees, building heights up to 20m, and wind loads up to 60m/s, to AS/NZS 1170.

What roof types is the Triangle Bracket suitable for?
It is designed for flat roofs and ground-mounted solar PV systems, and is rated for use on roof slopes up to 60 degrees and building heights up to 20m, in line with AS/NZS 1170 wind and snow load standards.
Does this listing include the fixing screws and clamps?
No. This bracket is supplied without screws or cross-connect clamps. Depending on your fixing method, you will need to order rail bolts, cross-rail brackets with hex nuts, or wood, metal, or hanger bolts separately.
What is the fixed tilt angle of this bracket?
The Fastensol Triangle Bracket sets the module array to a fixed 30 degree tilt angle, for panels fitted in portrait orientation.
What rail is this bracket compatible with?
It can be used with Fastensol's H-profile rail, attached using rail bolts, or with standard Fastensol rail, attached using cross-rail brackets with hex nuts.
What materials is the bracket made from?
The system components are made from stainless steel 304 and Al6005-T5 aluminium, giving strong corrosion resistance for outdoor flat roof and ground-mount installations.
