Stack Pins are the connectors that allow the stacking of scaffolding sets. We sell our scaffolding frames with stack pins and spring rivets included. The stack pin is fastened to the frame by way of a spring rivet. The spring rivet is compressed and pushed within the stack pin, the force created by this compression pushes two protrusions on the rivet out, through two holes in the stackpin which align with two similar holes in the frame's tube, holding them together.


We sell our frames with stack pins in them, to stack scaffolding sets one simply sets the second set atop the first, the bottoms of the main vertical tubes on the top set meeting with the stack pins protruding from the top of the lower set. The top half of the stack pin enters the bottom of the next set, where the holes on the legs of the frame align with the holes in the stack pin. The straight portion of a pig tail is placed through the tube, the curved portion falls into congruence with the scaffolding tubes curvature, holding the pigtail in place.
