Frequently Asked Questions
What is a solar L Foot?
A solar L Foot is a mounting bracket used to connect a PV mounting rail to a roof attachment or supporting structure. It forms part of the roof-to-rail connection in a rail-mounted PV system.
What size L Foot do I need?
The required L Foot size depends on the roof attachment, mounting rail, required clearance, fastening method, and project loads. Common L Foot configurations are available in different heights, widths, thicknesses, and slot dimensions. For a specific project, provide the rail and roof attachment dimensions for configuration review.
What are the typical dimensions of a solar L Foot?
Common reference dimensions vary by design. Typical aluminum L Feet may use approximately 4–6 mm material thickness, 40–120 mm height, 50–70 mm base length, and 40–60 mm base width, with mounting slots commonly around 9–11 mm. These are reference ranges rather than fixed specifications. Custom dimensions are available.
What material is used for solar L Feet?
Aluminum alloys such as AL6005-T5 are commonly used because they provide a useful combination of low weight, mechanical performance, corrosion resistance, and manufacturing consistency. Stainless steel configurations are also available for applications requiring different material or environmental performance. The actual material should be selected according to the complete mounting-system design.
What is the difference between a standard L Foot and a slotted L Foot?
A standard L Foot uses fixed holes or a defined fastening position. A slotted L Foot provides additional adjustment during rail positioning and can help accommodate installation tolerances. The actual adjustment range depends on the slot geometry and fastening system. IronRidge, for example, uses a vertical slot to facilitate rail installation and adjustment.
Can an L Foot be used with a hanger bolt?
Yes. L Feet can be configured with hanger-bolt assemblies for compatible roof applications. The required L Foot hole, plate, bolt size, washer, sealing component, and rail interface depend on the specific system.
Can the same L Foot be used with different solar rails?
Not necessarily. Rail compatibility depends on the rail slot, bolt head, rail nut, fastening dimensions, and available adjustment. If you provide the rail profile or dimensions, the L Foot interface can be reviewed and customized if necessary.
Does the L Foot include an EPDM pad?
An EPDM pad can be supplied depending on the configuration and roof application. For roof-penetrating applications, the sealing method should be evaluated as part of the complete roof attachment rather than treating the L Foot alone as a waterproofing component.
Can you provide a complete L Foot kit?
Yes. Depending on the application, a complete kit can include the L Foot, rail bolt, rail nut, washers, roof fastener, hanger bolt, EPDM pad, or other specified components. The BOM can be configured according to the customer's mounting system.
Can you customize the L Foot?
Yes. OEM/ODM customization can include dimensions, thickness, holes, slots, rail interface, roof attachment interface, fasteners, materials, surface finish, branding, and packaging.
Can you make an L Foot from our existing sample?
Yes. An existing sample, drawing, rail profile, roof attachment, or even dimensions and photographs can be used as the starting point for an OEM/ODM review. This is particularly useful when replacing an existing supplier or developing a proprietary mounting system.
