putlog couplers are used for fixing putlog tubes onto ledger tubes. similarly, they can be used for connecting transoms to ledger tubes and securing guard rails to standards. putlog couplers join 48 o.d. scaffold tubes at right angles. we fabricated your putlog coupler with customized bolt and nut:
21mm cross nut with washer
22mm flange nut for europe&america
23mm flange nut for australia
connects putlog or transom tubes to ledger tubes for the support of scaffold boards.
the one-piece body has been carefully designed and press-formed to provide the maximum resistance.
used for connection of putlogs & transoms to ledgers
compatible with all scaffold systems: slung scaffold, prefabricated scaffolding, putlog scaffold
Easy maintenance.
Because couplers themselves are not easy to rust and break, maintenance is very convenient after use, which not only reduces the difficulty of maintenance, but also saves the maintenance cost, reduces the manpower and material resources of maintenance, and increases the efficiency and quality of construction.
Strong corrosion resistance.
After passivation and galvanizing, the anti-rust ability of the whole piece is greatly improved, and its service life is long, far exceeding the service life of pressed couplers.
Strong resistance to stripping.
With the new connection, the new nut ensures that the pressed couplers can be fixed vertically and firmly in the case of steel tube deformation, eliminating the possibility of steel tube slippage.
Strong anti-deformation ability.
Compared with the ordinary pressed couplers, because of the different manufacturing processes, it breaks through the limitation of the traditional stamping process on material thickness， which can completely guarantee the non-deformation in the use process, thus ensuring the safety and reuse of products.
