SunLock Solar Panel Mounting L Foot

SunLock Solar Panel Frame Mounting System - L Foot (Steel roof)

The SunLock L-Foot (Steel roof interface) is used at regular intervals along the SunLock rail to secure the rail to the roof or structure of the building (roughly 1 per panel along the length of each rail - see brochure for more detail on quantity requirements). 

Installation: SunLock L-feet are first fixed in a straight line along the length of the the proposed rail location (in the purlins beneath the roof material), then the rail is fixed to the upright tabs on each SunLock L-Foot. An elongated rail fixing hole in the upright tabs ensures any undulations in the roof line are compensated out of the frame therefore eliminating physical stress on the delicate solar panels. Each SunLock L-Foot is supplied with a general purpose roofing screw for fixing to timber of steel bearers.

Like all SunLock framing clamps, a 6mm allen key is the only tool needed to secure the clamp. Sold as an individual item.

Here's three of many good reasons to choose the SunLock solar panel mounting system!

Australian Made - SunLock is an Australian designed and manufactured solar panel mounting system. Utilising custom designed and built aluminium extrusions and components, the SunLock system’s design greatly streamlines construction and improves frame strength in comparison to other systems.

Adaptability - SunLock’s significantly higher strength-to-weight ratio allows more efficient use and greater spans. Its highly versatile design offers adjustability and expandability to suit any job size.

Durability - Made entirely from aluminium and stainless steel, SunLock framing is suitable for long-term installation in all environments. SunLock framing is also backed by a 10 year warranty and is fully compliant with the Australian/New Zealand standard on wind actions AS/NZS 1170.2.2002, making it suitable for a wide variety of building types and climatic zones.

Ultimate Wind Load Capacity

Structural design analysis confirms the following ultimate wind loads supported by SunLock framing.

Maximum Serviceable Wind Loading

The table below describes the maximum serviceable wind loading that SunLock rails can support in reference to a maximum deflection of span/200 (Span/200 is considered the maximum acceptable deflection limit for SunLock rails supporting solar panels).
