Abstract
An apparatus for retaining and securing elevated objects such as cement valves. A harness member is wrapped around the outer surface of an elevated object, and adjustable straps are tightened to secure the harness member in place. An elongate sling member, attached the harness member, is securely attached to a cement head assembly or other nearby support structure. The apparatus provides positive retention should an elevated object become detached, thereby preventing the object from falling and injuring personnel or damaging property.
