Stack Pin & Spring Rivet Combo – 1.34″ OD (#6)

One piece, two jobs: a 1.34″ OD stack pin (#6) with a factory-installed spring rivet that speeds assembly and helps keep stacked frames locked together. Engineered for daily jobsite use, this combo arrives ready to work—no fiddling with loose hardware. The spring rivet is already seated inside the pin, so you can pin, snap, and move on. Its corrosion-resistant steel construction provides long-life protection against rust, and the positive “snap-through” action helps prevent uplift and maintain frame alignment. Designed for ScaffoldMart scaffolding frames that accept 1.34″ OD pins, it’s a simple upgrade that adds confidence to every stack. Why this combo helps Preinstalled Convenience: Spring rivet comes installed in the pin to save time, reduce dropped parts, and simplify setup. Corrosion-Resistant Build: Durable steel and protective finish stand up to weather and wash downs for longer service life. Stable, Aligned Stacks: Positive engagement helps limit uplift and keeps frames aligned as you build higher. Made for Fit: 1.34″ OD pin sized for yellow ScaffoldMart frames (does not fit our #5 tube [1.5″ OD] premium frames). Installation Tips Seat the pin fully, then verify the spring rivet snaps through the frame hole before loading the tower. Confirm your frame style and hole size match a 1.34″ OD stack pin. Inspect pins and rivets for wear, bending, or corrosion; replace any damaged hardware before use. Important Note Use only with frames designed for 1.34″ OD stack pins. Do not mix pin sizes or use damaged components; always follow your company safety plan and local code.
