How do you properly bend and install a slip and drive (S&D) connection?

Plain-English answer

1. The Slips (S-cleats) go on the flat, wider sides of the rectangular duct (typically top and bottom). 2. The Drives go on the short sides containing the pre-formed 1/2-inch drive cleat hooks (typically left and right). 3. Slide the S-cleats onto the raw metal edges of the first duct. Push the matching duct piece into the other side of the S-cleats. Slide the drive cleats down the side hooks, and bend the excess top/bottom tabs over tightly to lock the joint.

Field checklist

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

Ask Foreman

Hey boss, I’m on duct assembly and need verification before I touch this: How do you properly bend and install a slip and drive (S&D) connection? Do you want me to stop here and check the approved detail, submittal, or inspector/manufacturer requirement first?

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.
