StiffClip® LB Spandrel/Multi-Purpose Clip
The StiffClip LB series connects exterior wall studs to the building’s structure through a unique design incorporating the use of stiffened legs of a 90° angle to increase bending strength. StiffClip LB resists horizontal and vertical loads.
Features
- Various lengths allow for construction tolerance
- Guide holes for attachment to structure and stud
- Replaces expensive bracing
- Structurally load tested

Blast & Seismic Design
The Steel Network is the only connector manufacturer in the US that has rated its connector products for special seismic and blast design by providing tables with LRFD design strength, nominal strength and ultimate strength for each connector.

StiffClip® LB Applications
The attachment of StiffClip LB to the primary structure may be made with PAF’s, screw/bolt anchors or weld and is dependent upon the base material (steel or concrete) and the design configuration.

StiffClip® LB Installation Instructions
- Secure LB to pour stop with engineered attachment.
- Connect clip to stud with approved screws (not provided by TSN).
StiffClip® LB Allowable Loads
Load Table Notes:
- Design loads are for attachment of StiffClip LB to stud only. Load tables reflect in plane of wall loads (F1), horizontal loads (F2) and vertical loads (F3).
- Design loads consider loads on the clip and #12 screw fasteners to the stud web.
- 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.
- Torsional effects are considered on screw group for 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.
- Attachment to structure engineered by others.
- Allowable loads have not been increased for wind, seismic, or other factors.
- Allowable load tables incorporate eccentric loading of fasteners. Values with a welded connection may increase.
- Fasten within 3/4″ from the angle heel (centerline of the 1-1/2″ leg) to minimize eccentric load transfer.
- Strengthening ribs are present in 3-5/8″, 6″, and 8″ clip sizes. 10″ and 12″ clip sizes contain 1/2″ return lips on the top and bottom of the leg attaching to the stud for increased stiffness.
- For LRFD strengths contact TSN technical services.
Screw Pattern Notes:
**Important Consideration: Pattern diagrams indicate fastener placement only. Standard StiffClip LB products come with 4 predrilled guide holes as depicted in Pattern 3 for LB362, LB600, and LB800 and depicted in Pattern 13 for LB1000 and LB1200. Alternate patterns can be utilized in the field or be accommodated as a TSN special part request. Contact TSN Sales for information regarding special part requests.
Load Direction
LB600-HD Notes:
- Design loads are for attachment of StiffClip LB-HD to stud only. Load tables reflect in plane of wall loads (F1), horizontal loads (F2) and vertical loads (F3).
- Design loads consider loads on the clip and #12 screw fasteners to the stud web.
- 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.
- Torsional effects are considered on screw group for 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.
- Attachment to structure engineered by others.
- Allowable loads have not been increased for wind, seismic, or other factors.
- Guideholes for stud connection are 0.172″ diameter for #12 screws. Guideholes for structure connection are 3/8″ diameter for (2) 1/4″ diameter anchors.
- Fasten within 3/4″ from the angle heel (centerline of the 1-1/2″ leg) to minimize eccentric load transfer.
- For LRFD strengths contact TSN technical services.
