Mounting device for a metal roof

A clamp system for a bulb seam on a building surface, comprising:

• a clamp comprising:
• a body having a first end, a second end, a lower surface, and a first side, the body including a recess than extends along a rotation axis between the first and second ends of the body;
• an aperture extending through the body having an aperture axis that is oriented to intersect a receiving space;
• a first arm that extends from the first side of the body to a first distal end, wherein the first arm has a first inner surface that is concave;
• and
• an insert having a second arm that extends from the body to a second distal end and that has a second inner surface that is concave, the insert including a protrusion at a proximal end, wherein the second arm extends from the lower surface of the body when the protrusion is positioned within the recess of the body,
• wherein the receiving space defined by the first inner surface of the first arm and the second inner surface of the second arm has a substantially circular cross-sectional shape to extend around the bulb seam,
• wherein a width of the receiving space of the clamp defined between the first inner surface of the first arm and the second inner surface of the second arm is adjustable with rotation of the insert relative to the body between a first position and a second position via engagement of the protrusion of the insert within the recess of the body, and
• wherein the first arm is fixed in position relative to the bulb seam during rotation of the insert between the first position and the second position;
• and
• a bar component selectively extendable through the aperture for engagement with the insert.

A clamp configured to engage a bulb seam of a building surface, comprising:

• a body including a first arm with a first inner surface that is concave, a first distal end having a first finger, and a recess positioned within the body and spaced a predetermined distance from the first arm;
• an insert spaced a predetermined distance from the first arm, the insert including a second arm extending from a protrusion operable to engage the body, the second arm including a second inner surface that is concave and a second distal end having a second finger;
• an aperture disposed through the body having an aperture axis oriented at an angle that intersects a receiving space;
• and
• a leg extending from the body opposite the first arm, wherein the recess of the body is positioned within the body between the first arm and the leg,
• wherein the receiving space defined by the first inner surface of the first arm and the second inner surface of the second arm has a substantially circular cross-sectional shape to extend around the bulb seam, the receiving space formed from the first inner surface and the second inner surface,
• wherein the first finger and the second finger are directed toward the receiving space,
• wherein a width of the receiving space of the clamp defined between the first inner surface and the second inner surface is adjustable with rotation of the insert relative to the body between a first position and a second position via engagement of the protrusion of the insert within the recess of the body, and
• wherein the insert rotates in a space defined between the first arm and the leg about the bulb seam between the first position and the second position relative to the first arm that is non-rotational.
