Simpson Strong-Tie DRIFT CLIP 3.5x5.5x4 12GA 25PAK W/SCREWS-9907

Engineered Drift-Clip Connector for Bypass Stud-to-Slab Applications

The Simpson Strong-Tie IDCB Drift Clip 9907 is a precision-engineered solution for securing bypass light-gauge steel studs to slab edges, allowing for controlled movement under dynamic loading conditions. With built-in allowances for both vertical deflection and lateral drift, this system is ideal for high-performance steel frame structures in seismic or wind-prone regions.

Key Features

• Deflection and Drift Accommodation
  Allows for 25mm of vertical movement (upward and downward) and 25mm of lateral drift in each direction—crucial for preserving structural integrity in dynamic environments.

• Optimised F2 Load Performance
  Horizontal embossments and corner gussets are engineered to maximise strength and reliability in the F2 load direction (perpendicular to the wall).

• Precision Shouldered Screws Included
  Each pack includes purpose-designed Strong-Drive® XL screws that prevent overdriving and ensure accurate installation for full movement allowance.

• Slotted Design with Centre Marks
  Vertical and horizontal slots feature No-Equal centre stamps, assisting in correct screw alignment and anchorage to steel edge angles.

• Steel Edge Anchorage Ready
  Load values are tested specifically for Ø5.5 x 32 mm screws anchoring into steel edge angles, ensuring verified structural performance.

Benefits

• Absorbs Structural Movement
  Provides a controlled interface between studs and slabs, reducing risk of deformation or failure due to seismic, wind, or thermal activity.

• Time-Saving Installation
  Clearly marked slots and pre-supplied screws help installers achieve correct alignment without measurement guesswork.

• Consistent and Tested
  All connectors are pre-tested for performance with supplied fasteners, ensuring code-compliant, repeatable results.

• Durable Construction
  Manufactured from 12-gauge pre-galvanised steel for long-term resistance in protected structural environments.

1. XLQ114B1224 screw centred in each horizontal slot. Back out screw 1/2 turn after installation of clip. 2. XLSH78B1414 centred in each vertical slot.

Installation Notes

1. Install one XLQ114B1224 screw centred in each horizontal slot and back out ½ turn after setting the clip.

2. Install one XLSH78B1414 screw centred in each vertical slot.

3. Ensure all centre markings align for optimal performance.

4. Do not overdrive screws; shouldered design ensures correct set depth.

Important Notes

• Not suitable for exterior or unprotected environments without additional corrosion protection.

• Anchorage should be into verified steel edge angles using supplied fasteners only.

• Always refer to the latest Simpson Strong-Tie technical documentation for design load tables and code compliance.
