Flat-to-Roof Mounting System
A solar PV array can be installed flush on a roof using SunLock channel instead of rail. This can decrease parts cost by ~ 5% and also decrease installation time. Furthermore, the channel forms a conduit for cabling.

GUIDE TO USE
On typical steel framed commercial buildings the solar PV modules will be installed in landscape with SunLock channel running from the gutter to the ridge cap. Use two channels per column of modules.
Fix the channel to the purlins using channel feet and standard roofing screws. Fix the modules to the channel using mid-clamps and end-clamps with channel nuts.
A key advantage of channel is that a channel foot (SLCF3) can accept two roofing screws, instead of the single screw in the base of an L-foot.

FEATURES
SunLock new commercial flush system eliminate the need of Earthlock washers. The earthing component are built into the mid clamp. Further cuts down the time of installation.
You could also runs your cable in the channels so less cable clip needed when installing the systems. The whole idea of our commercial product is to save installer time so more of the solar project budget could be used on a better and more rigid product.
25 years warranty is included in all commercial racking systems.
CERTIFICATION AND FIXING SPACING
Use the indication in the general engineering certificate to determine the fixing spacing on the roof, available upon request. These are valid for flush mounting onto roofs with a steel purlins and a 5-30 degree pitch, TC2 or TC3 in Region A.
Note that because the SLCF3 channel foot can accept two roofing screws instead of the single roofing screw in an L-foot, the fixing spacing can be increased up to 1800 mm, where the rail/channel is the limiting factor.
