Abstract: A saddle clamp assembly includes a hollow cylindrical body centered about a longitudinal axis and being diametrically split into semicircular top and bottom sections each having a pair of radially outwardly projecting connection flanges at their opposite ends. A pair of bolts are captively retained on the top section flanges and are threadable into nuts captively retained on the bottom section flanges. A base member is anchored to a central underside portion of the bottom clamp body section and has a pair of connection tabs positioned beneath the bottom clamp body section connection flanges on opposite sides of the clamp axis. A pair of bolts are captively retained on the base member connection tabs and are threadable into a pair of nuts captively retainable on a support structure. The connection tab and connection flanges on each side of the clamp body are axially offset in a manner permitting downward installation/removal tool access to the lower bolts past the connection flanges.
