Spacer Bar Application and Desiccant Fill Inspection

Inspection template for verifying spacer bar bend quality, corner keys, splice joints, and active desiccant quantity during IG assembly to help prevent moisture ingress and premature seal failure.

Inspection Setup and Run Identification

• Run, line, and product identification recorded
• Inspection performed at the correct IG assembly stage
• Spacer bar and desiccant materials match the approved specification

Spacer Bar Bend Quality and Fit

• Spacer bar bend quality is smooth and free of kinks, flattening, or distortion
• Spacer bar dimensions and corner geometry match the frame pattern
• Spacer bar sits flush with no visible gaps at contact points
• Spacer bar surface is free of damage, contamination, or deformation that could affect sealing
• Measured spacer bar fit within acceptable tolerance
  Record the measured gap, deviation, or fit error in millimeters. Use the approved work instruction for the exact tolerance limit.

Corner Keys and Splice Joints

• Corner keys are fully seated and properly aligned
• Corner joints are tight with no visible separation or misalignment
• Splice joints are secure and continuous without openings or step changes
• Joint areas are free of burrs, cracks, or other non-conformances
• Approved adhesive, sealant, or fastening method applied per specification

Desiccant Fill Verification

• Active desiccant quantity meets the specified fill requirement
  Enter the percent of required fill achieved for the spacer bar cavity or the measured quantity per the approved specification.
• Desiccant is active, dry, and free-flowing at time of fill
• Desiccant fill is continuous with no voids, bridging, or overfill at corners
• Fill ports or openings are properly closed after desiccant loading

Defects, Corrective Action, and Release

• Deficiencies or non-conformances documented with location and description
• Corrective action assigned and verified before release
• Inspector release authorization completed
