K2 Systems SingleHook 4S Stainless Steel Roof Hook for Tiled Roofs, Adjustable Height 120-155 mm, for SolidRail and MiniRail

On a pitched tiled roof, securing PV modules demands a mounting point that can handle shifting batten heights and harsh weather without corroding. The K2 Systems SingleHook 4S delivers that reliability: a stainless steel roof hook engineered for tiled roofs, compatible with K2 SolidRail and MiniRail systems. Its adjustable height range of 120–155 mm (40–75 mm under batten) ensures precise alignment, while the angled 30 mm hook and 140 x 55 mm base plate distribute load effectively, protecting roof tiles and providing a stable foundation for your solar array.

Key specifications

• Material: Stainless steel A2, 6 mm thick, natural silver finish

Why choose it

Stainless steel construction ensures long-term durability even in coastal or high-humidity environments, resisting corrosion where standard steel would fail. The adjustable height range allows installers to adapt to varying batten positions without custom fabrication, speeding up installation and reducing errors. The angled design minimizes stress on roof tiles, helping maintain waterproofing and structural integrity.

Ideal use cases

• Residential and commercial PV installations on tiled roofs
• Projects using K2 Systems SolidRail or MiniRail mounting rails
• Retrofitting solar panels where batten spacing varies
