A bracket assembly is provided that includes a first strap, a second strap, and a first fastener. The first strap has an openable aperture including a cutout operatively connected to a keyhole. The second strap has a first aperture positioned opposite the cutout. The first fastener has a head, a neck, and a shaft. The neck is receivable in the openable aperture of the first strap with the shaft received in the first aperture of the second strap. The first fastener and the openable aperture allow the shaft to pass vertically between the cutout and the keyhole, but prevent the neck from vertically passing through between the cutout and the keyhole. The first fastener and the openable aperture allow the head to pass axially through only the keyhole.
