Global Pipe Brand Connectors
Your review: I used about 20 of these in various configurations recently. All were as described - no problems with any of the castings. All of the hex head screws threaded cleanly and easily. Great product overall at a good price.
Pros: Makes assembling frames out of 1 1/4 ID pipe very easy. Castings in good shape. Hex head screws threaded cleanly and easily
Cons: No real cons - it's a simple product and it does the job well. Tiny point - make sure to degrease these if you plan on painting them.
