Abstract: A clamping system includes a mast, a bracket clamp engageable with the mast, the bracket clamp including a receiver for receiving a sign, a compression assembly for compressing the mast and the receiver towards each other, and a compression element movable relative to the receiver by the compression assembly, the compression element contacting a side surface of the mast via a plurality of contact features, each contact feature contacting the side surface of the mast at a distinct location on the side surface of the mast.

Abstract: A clamping system includes a mast, a clamping body engageable with the mast, the clamping body including a plurality of side surfaces, a compressive member for compressing the mast and one of the plurality of side surfaces towards each other, and a vertical support member, the vertical support member disposable between the one of the plurality of side surfaces, the mast, a second of the plurality of side surfaces and a third of the plurality of side surfaces, the one of the plurality of side surfaces, the second of the plurality of side surfaces, the third of the plurality of side surfaces and the mast each facing a different side of the vertical support member when the vertical support member is disposed between the one of the plurality of side surfaces, the mast, the second of the plurality of side surfaces and the third of the plurality of side surfaces.

Abstract: A folding system includes a folding mount rotatably attached to a handle, the folding mount being selectively positionable in a folded state and an extended state, a bolt rotatably connecting the folding mount to said handle, a bore formed in the handle, the bolt being disposed at least partially within said bore and the bore defining a bore axis, a boss and a counterbore formed in the handle, the boss including a boss surface substantially perpendicular to the bore axis and a boss angled surface offset from the boss surface by a first acute angle, the counterbore including a counterbore surface substantially perpendicular to the bore axis and a counterbore angled surface offset from the counterbore surface by a second acute angle.
