Solar Mounting Made Simple Engineering Design Guide R System Parts Top Cap The IronRidge Top Caps facilitate the quick and easy construction of a Schedule 40 substructure. Available in sizes that fit either 2” or 3” Schedule 40 pipe, this Top Cap secures quickly to multiple pier types with 3 set screws and also supports cross piping (schedule 40) with U-bolt hardware. Property Value Material ALMAG 535 Finish Mill Top Cap Sizes 2” and 3” 2” Top Cap Dimensions 3” x 4.
Solar Mounting Made Simple Engineering Design Guide R System Parts Rail Connector Our Rail Connectors secure IronRidge Standard Rails to the Schedule 40 horizontal cross pipes. Each Standard Rail requires two connectors to create a secure attachment.
Solar Mounting Made Simple Engineering Design Guide R System Parts Mid Clamps IronRidge Mid Clamps secure PV modules to the rail when there are multiple modules in a row. The Mid Clamp fits between two adjacent modules, providing clamping pressure to both modules simultaneously. The Mid Clamps are not dependent upon the PV module’s mounting holes and fit to the top slots of our Standard Rails.
Solar Mounting Made Simple Engineering Design Guide R System Parts Grounding Wiley grounding clips (WEEB DMC) are used in conjunction with the IronRidge Mid Clamps for grounding PV modules to the Standard Rails. Order one grounding clip for every two Mid Clamps used.

Solar Mounting Made Simple R Engineering Design Guide Engineering Data Ground Mount Foundation Requirements The foundation requirements for a cast-in-place drilled concrete pier system may be obtained from Tables 3 & 4. These tables are based on the piers being installed at their maximum allowable spacing. For spacing’s less than maximum and for loads cases with snow > 0 psf, the requirements can be determined by using the online Design Assistant at ironridge.com/sga.
