Mounting device for building surfaces having elongated mounting slot

A mounting system to secure a structure to a rib of a metal panel, comprising:

• a mounting bracket including:
• an upper wall with a first end spaced from a second end in a longitudinal dimension, a mounting aperture that extends through the upper wall, and a lower surface that faces an endwall of the rib when the mounting bracket is secured to the rib;
• a first sidewall extending from the upper wall to a first sidewall end and which has a first interior surface that faces a first side of the rib when the mounting bracket is secured to the rib, a first exterior surface opposite the first interior surface, and a first fastener hole extending through the first sidewall;
• a second sidewall extending from the upper wall to a second sidewall end and which has a second interior surface that faces a second side of the rib when the mounting bracket is secured to the rib, a second exterior surface opposite the second interior surface, and a second fastener hole extending through the second sidewall;
• a first gasket positionable between the first interior surface and the first side of the rib when the mounting bracket is secured to the rib;
• a first fastener extendable through the first fastener hole, the first gasket, and the first side of the rib to secure the first sidewall to the rib;
• a second gasket positionable between the second interior surface and the second side of the rib when the mounting bracket is secured to the rib;
• a second fastener extendable through the second fastener hole, the second gasket, and the second side of the rib to secure the second sidewall to the rib;
• a clamp securable to the upper wall of the mounting bracket and including a base positioned proximate to the upper wall of the mounting bracket, an extension, and an engagement portion extending outwardly from the extension to secure the structure to the rib when the clamp is secured to the mounting bracket;
• and
• a clamp fastener to selectively secure the clamp to the mounting bracket, the clamp fastener extendable through the mounting aperture.

A mounting device to engage a rib of a metal panel, comprising:

• an upper wall with:
• a first end;
• a second end separated from the first end in a longitudinal dimension by a first length;
• and
• a mounting aperture extending through the upper wall, wherein the mounting aperture is unthreaded;
• a first sidewall extending from the upper wall to a first sidewall end and having:
• a first interior surface;
• a first exterior surface;
• a first fastener hole extending through the first sidewall;
• and
• a first sidewall length extending in the longitudinal dimension and measured proximate to the first sidewall end;
• a second sidewall spaced from the first sidewall in a lateral dimension, the second sidewall extending from the upper wall to a second sidewall end and having:
• a second interior surface;
• a second exterior surface;
• a second fastener hole extending through the second sidewall;
• and
• a second sidewall length extending in the longitudinal dimension and measured proximate to the second sidewall end, the second sidewall length being approximately equal to the first sidewall length;
• a first width between the first sidewall and the second sidewall measured in the lateral dimension proximate to the upper wall;
• and
• a second width measured in the lateral dimension between the first and second sidewall ends, the second width being greater than the first width.
