TinnerFlow™2nd YearAnchors / Sloped Beam FaceYELLOW · Check First
Do not force a nut and washer tight against a sloped face. Square the bearing surface or use an approved swivel/angled support so the rod hangs plumb.
A hanger rod wants to pull straight down. If the anchor seat is on a sloped beam face, tightening the hardware can bend the rod and side-load the anchor.
Check whether the support can be moved to a flat substrate. If not, the usual fix is an approved bevel washer, shim plate, swivel insert, or engineered bracket that keeps the load vertical.
Do not bend hanger rods sideways and call it “close enough.”
Side-loaded rods and anchors can loosen, fatigue, or fail, and they make the duct line drift out of level.
Final direction still comes from approved drawings, specs, manufacturer instructions, employer policy, foreman/detailer direction, structural/seismic details, and AHJ/code requirements.
