Great product very well made

I purchased these for replacement parts for other branded scaffolding. Pros… works ok in a pinch and for non-commercial use in other brands of scaffolding. Cons….Doesn’t fit snug, OD was smaller and 1” ‘shoulder’ is rather wimpy as well. I used a sleeve of modified 1” EMT conduit to bulk up the bottom half and it helped. Replacing the 1” ‘shoulder’ with a piece of 1-1/4” rigid conduit would have also made it almost perfect. Since the overall length only comes in one size, they are more irritating to use when stacking on the next section. My original ones had one longer coupling, allowing me to engage one end of the second tier’s post and then the other end (of that section posts)

The pins were satisfactory, but they were not the size needed for the scaffolding we have. I assumed that since the TSC scaffolding frames were yellow (which I believe is a standard color coding), they would fit our yellow frames. Unfortunately, they are not big enough.
