StiffClip® AL
The 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.
Features
- 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 Applications
The attachment of StiffClip to the primary structure may be made with PAFs, screw/bolt anchors or weld and is dependent upon the base material (steel or concrete) and the design configuration.
All Purpose Rigid Connector - Window Sill
Installation Instructions
- 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.
