The Scaffold Pro 3 scaffold ratchet is our newest product. It has a longer socket than the Pro 1, but longer than the Pro 2. The handle is longer than the Pro 1 or 2 and has a larger thumb lever. The larger thumb lever allows for easier shifting when wearing gloves. The Pro 3 has a finer tooth gear for smoother operation and more clicks in tight places.
Dual size scaffolding systems allow companies to mix and match poles with the same clamps. This saves money, but caused a unique problem. That is most scaffold ratchets are not deep enough to fit over the nuts when the clamps are used on smaller scaffold tubes. The problem is excess threads extending way beyond the nut keeps the socket from fitting down all the way.
Dual Size Scaffold Couplers are used mainly in nuclear power plants and shipyards, but are found increasingly in refineries and construction sites.
