StiffClip® AL

StiffClip® AL is a versatile, multi-purpose rigid connection for use in a wide variety of applications. Pre-drilled holes facilitate quick and accurate fastener placement to structure and/or framing members. Stiffeners in each angle leg add to overall clip strength. StiffClip AL is tested to resist loads in 3 separate directions: horizontal, vertical, and lateral. Use of certified steel, combined with tested load values ensures construction professionals will achieve optimal structural performance.

Value

  • Guide holes for fast and accurate connections
  • Stiffeners for additional strength
  • Manufactured from certified, 50ksi steel
  • No labor spent cutting scrap angle
  • Used in a variety of applications
  • Extensively tested (reduces liability concerns associated with use of untested, miscellaneous untraceable material)

Material Composition

ASTM A1003/A1003M Structural Grade 50 (340) Type H, ST50H (ST340H): 50ksi (340MPa) minimum yield strength, 65ksi (450MPa) minimum tensile strength, 68mil minimum thickness (14 gauge, 0.0713” design thickness) with ASTM A653/A653M G90 (Z275) hot dipped galvanized coating.

StiffClip_AL_Application_Images

Four #12 screws are attached to member through predrilled guide holes in the 3” leg. Attach short (1.5”) leg to structure/member either utilizing the pre-drilled guide holes or with weld (attachment through short leg is engineered by others). If pre-drilled holes are not able to be utilized, follow fastener manufacturer recommendations for screw placement.

Notes:

  • Allowable load tables incorporate eccentric loading of fasteners attached 3/4" from the heel of the clip. Values with welded connection may increase.
  • The attachment of the 1.5" leg of StiffClip AL is dependent on the allowable loads of the fasteners, and is to be designed by others.
  • Fasten within ¾" from the angle heel (centerline of the 1½" leg).
  • All guide holes may not require fasteners. Number of fasteners used is to be determined by designer.
  • Stiffening ribs are not present in the AL800.
  • StiffClip AL is tested to resist loads in horizontal, vertical, and lateral directions.
  • Loads listed reflect force in a single direction. When multiple loads react on the connection, it is the responsibility of the designer to check the interaction of forces.
  • Allowable loads are for attachment through 3" leg only. Attachment through 1.5" leg should be engineered. (See material composition above for calculation purposes.)
  • Allowable loads have not been increased for wind, seismic, or other factors.
  • Torsional effects are considered on screw group for F2 & F3 allowable loads. It is assumed that half of the torsional moment is taken by the connection to the structure and half is taken by the connection to the stud.
