About this detail

Suspension framing for a hanging mechanical unit supported from a steel joist and metal roof deck. An angle brace measuring L2x2x3/16 spans from the top chord bearing joint to the nearest bottom chord panel joint, matching detail 9/S522 similarly. A structural angle section L5x3x1/4 (long leg vertical) serves as the primary support, positioned beneath a spacer plate and connected to the hanging rod sized per mechanical plans. A drawing note specifies that where the mechanical unit weighs less than 300 pounds, a Unistrut section should be used to support the unit instead of the L5x3x1/4 angle.
