The Chief CMA340 Projector Stabilization Kit adds lateral bracing to long extension columns. Tall drops are prone to swaying from HVAC airflow, building movement or contact, and that motion shows up as a shaking image on the screen. The CMA340 clamps to a 1.5-inch NPT column and runs four cables out to the surrounding structure, where turnbuckles let the installer tension each line until the column is held firmly in place. The kit contains one pole clamp, four 10-foot cables and four turnbuckles, giving enough reach for most open-ceiling and high-bay installs. Chief lists a 500 lb weight capacity and TAA compliance. Anchors to the building structure are not included and should be chosen to suit the ceiling material. Combine with a vibration isolator such as CMA347 or CMA348 where building vibration is also an issue.
