2. A Bridge is not required at an east-west junction if each of the modules being joined with a
Bridge is within the cantilever requirement. For example, in the drawing below, Junction A
does not require a Bridge. At Junction B, the module on the right is properly cantilevered,
but the module on the left requires a Bridge to complete the span.
Note: A Bridge may be necessary for electrical bonding, even if it is unnecessary for structural
support (see Section 3.7 – Electrical Grounding).
3.5.2 North Bridge Thumb Screws
Any Bridge that does not have a module on the “north” side of the Bridge will require a thumb
screw to be installed. The yellow arrows indicate where Thumb Screws would be required on
the below array.
3.6 Trim and End Cap Placement
While Trim is never necessary for proper installation of an FX system, it is ALWAYS
recommended. It is recommended that any module with its south-edge fully exposed have Trim
installed.
Trim End Caps (L and R) are used to cover the exposed end of a Trim piece. If the Trim butts
up against a module (e.g. on the inside of stair-step array), no End Cap is necessary.
