What's the proper way to swage a Gripple or cable lock for a seismic sway brace

Plain-English answer

Thread the raw steel aircraft cable through the directional arrow path of the seismic lock block. Loop the cable tightly around your structural bracket attachment point, then feed it back through the secondary locking channel track of the block.

Use a calibrated mechanical swaging crimp tool to clamp down on the internal locking wedges or sleeves until they physically lock onto the cable core. Leave a minimum 3-inch tail wire sticking out past the block exit.

Field checklist

• Stop and verify the approved detail, manufacturer instructions, foreman direction, and project specs before touching it.

Verify before acting

Use this as training guidance. The foreman, approved drawings, project specs, manufacturer installation instructions, employer safety policy, and AHJ/code requirements always control the final answer.
