The Global Truss ST-157 is a robust and highly reliable 15.7-foot adjustable crank stand, designed to handle heavy-duty audio and lighting equipment in a variety of event settings. With a maximum load capacity of 330 lbs, the ST-157 offers exceptional support and stability for pro audio speaker cabinets and lighting rigs. Its versatile design features a multi-mast configuration that allows for a low loading height and ensures maximum rigidity, making it an ideal solution for both temporary and permanent installations in large venues and outdoor events.

One of the standout features of the ST-157 is its high-quality construction, designed with both strength and safety in mind. The telescoping masts are made from treated steel and have been specifically sized to provide optimal structural integrity while lifting heavy loads. The top mast features a 1-3/8" diameter steel tube, which is an industry-standard size for supporting pro audio speaker cabinets, ensuring the stand can handle the demands of professional equipment. Additionally, special attention has been given to the safety features of the stand. The spring-loaded safety pins provide extra security when operating the stand, preventing accidental adjustments during use. For even further safety, each mast can be secured with a tension knob to ensure stability while lifting or lowering heavy equipment.
