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)

StiffClip_AL_Example_Details

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.

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.

Note:

  • 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.
  • Allowable loads are for attachment through 3” leg only. Attachment through 1.5” leg should be engineered. (See material composition on previous page 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.
