The PLS4 bypass slab slide strut secures the bypass curtain wall stud to the building structure, allowing for vertical deflection while maintaining lateral rigidity. The strut provides a non-frictional connection and prevents vertical load transfer into the curtain wall.
Struts 12″ in length or shorter come packaged in durable buckets for convenient handling on the jobsite. The PLS4 is designed to replace the PLS3 clip.
Features & Benefits
- Slots allows for 2” total vertical deflection
– Deflection of 1″ up and 1″ down - Loads based on proprietary screws
– #14 shouldered screws are provided for ease of installation - Pre-punched guide holes
- Transfers horizontal load into structure
- Maintains lateral rigidity

Table Notes
- Allowable loads have not been increased for wind, seismic, or other factors.
- The allowable loads are based on the steel properties of the members being connected, per AISI S100.
- The nominal strength of the screw must be at least 3.75 times the allowable loads.
- Penetration of screws through joined materials should not be less than three exposed threads. Install and tighten screws in accordance with the screw manufacturer’s recommendations.
- Screw shear capacities are based on allowable strength design (ASD) and include a safety factor of 3.0.
- Allowable loads indicated on the table(s) are for force in single direction only. The designer shall use the combined forces check as required by AISI S100 if more than one force is applied to the connection.
- The designer shall check the bending in the short leg of clip.
