StiffClip® HE

The StiffClip® HE series is used when connecting either beams to columns or headers to jambs. StiffClip HE’s unique design incorporates stiffened ribs to protect the header ends from the effects of web crippling. StiffClip HE transfers horizontal and large vertical loads from the beam to the column while incorporating a small shelf tab for alignment of box header during installation. The allowable design load table shown below is based on the use of StiffClip when attached to various steel column and beam material thicknesses and yield strengths. The minimum combination of steel thickness and yield strength must be used when determining the maximum design load. Design loads listed below consider both loads on the clip and the #10 screws as they are fastened to the steel beam and column members.

Value

  • Guide holes for connections to column and box header
  • Resists vertical and horizontal loads
  • Acts as a web stiffener
  • Tabs to hold header during installation
  • Reduces material (no jack studs or caps required)
  • Reduces labor expense
  • Extensively tested

** Clips are packaged as pairs. Two left-hand and two righthand clips attach the complete header to the jamb.

  • Torsional effects are considered on screw group for F2 & F3 allowable loads.
  • Attachment to stud is made with screws symmetrically placed. All guide holes may not require fasteners. Fastener amount determined by designer.
  • Allowable loads have not been increased for wind, seismic, or other factors.
