China Scaffold Manufacturer
A yellow zinc joint pin coupler for connecting scaffold tubes end to end, available in BS 48.3 mm and JIS 48.6 mm types for scaffolding and tube and coupler scaffolding work.
A joint pin coupler is used when workers need to join two scaffold tubes in a straight line. It sits inside the tube ends and helps keep the connection aligned, so the scaffold tube can be extended without adding a bulky external fitting around the outside.
On-site, this small part saves space. That matters when the scaffold is already tight around walls, columns, platforms, or steel structures. For normal scaffolding work, it gives contractors a quick way to extend tube length while keeping the outside of the tube cleaner and easier to handle.
This scaffolding joint pin coupler works well in scaffolding systems, access scaffolds, temporary support work, industrial maintenance jobs, and tube and coupler scaffolding layouts where tube extension is needed.
It is not the same as a double coupler or swivel coupler. A double coupler holds tubes at 90 degrees, while a swivel coupler handles angled bracing. A joint pin coupler does a more direct job: it helps connect two tube ends in line, usually for vertical or straight tube extension.
This joint pin coupler with a tube connection of 48.3 mm × 48.3 mm can be used for the joints of scaffolding and BS-type projects. At about 0.63kg per piece, it requires additional heft to achieve a sense of propriety without compromising the handling speed. And processed with a yellow zinc finish, it is 25PCS/BAG, 50BAGS/PALLET, packed with the right size, and widely used in scaffold yards or large quantity orders.
For JIS-type projects, the pressed joint pin version fits 48.6mm × 48.6mm scaffold tubes. Each piece weighs around 0.64 kg, with a yellow zinc surface. The packing is 30 PCS/BAG, 50 CTNS/PALLET, which works better for buyers serving Japanese, Korean, or other markets that commonly use 48.6 mm scaffold tube sizes.
A joint pin coupler may not look like the most complicated scaffolding coupler, but rental yards and contractors use it all the time because tube extension is a daily job. When a crew needs longer standards, temporary alignment, or cleaner tube joints, this fitting is usually the simple answer.
The yellow zinc finish helps protect the surface during sea shipping, warehouse storage, and outdoor site use. Together with clear bag and pallet packing, it makes stock counting easier for importers, distributors, and scaffolding parts suppliers. Nothing fancy here — just a useful fitting that needs to be the right size, easy to count, and ready when the project starts.
