Q. How much weight can a lighting truss hold?

Answer

Using a proper truss lighting clamp a user may quickly and easily attach lighting equipment to truss. Clamps and couplers are available in a wide variety from manufacturers to accommodate truss types and loads of up to 500kg. Most garage trusses include horizontal bottom chords strong enough to support the weight of drywall and insulation. Therefore if the ceiling is completed a user has some extra weight capacity: At most need to account for 5 lbs. per square foot. A 2 × 4-foot piece of plywood could be laid across the chords and supported the equivalent of 40 pounds. The weight must be dispersed throughout the cords so make sure the things are separated out.
