Drop Forged Scaffold Double Coupler for Tube and Clamp Scaffolding
Double Coupler Scaffolding for Fixed Tube Joints
Double coupler scaffolding is widely used, as it offers basic right-angle provision in between tubes through the coupler, and it makes the structure stable during the erection process itself and while being used on a daily basis. A good quality scaffold double coupler contributes to a more stable joint, keeps ledgers and standards aligned, and offers the contractors a more consistent fitting when employing repeated site work. In full scaffolding systems, this component is directly correlated with rigidity, connection safety, and installation efficiency.
Double Coupler Types for Different Market Needs
Huilai supplies drop forged double coupler products in a standard 48×48 mm size with Q235B material. We offer BS type, German type, Italian type, and US type options to match different regional preferences and project standards. Surface treatment includes EP and HDG, giving buyers practical choices for appearance, corrosion protection, and service life in outdoor scaffolding use.
Double Couplers with EN74 and Weight Options
Our double couplers cover several practical weight ranges without changing the core 48×48 mm connection format. BS-type products are available from 0.95 kg to 1.05 kg with EN74 compliance. German type options range from 1.07 kg to 1.18 kg and are available in EN74 or EN74 Class B. Italian type versions weigh 1.27 kg and 1.65 kg, while the US type option weighs 1.5 kg and meets EN74 Class B. This range helps buyers choose the right scaffold double coupler according to market requirements, handling preferences, and project demand.
Supply Support Across Scaffolding Systems
Huilai is a scaffolding factory for importers, distributors, and contractors who need quality fittings to create complete scaffolding systems. We offer a scaffolding coupler for wider uses in scaffolding systems, as well as full tube and clamp scaffolding solutions.

PRODUCT FAQ
FAQ for Scaffold Product Buyers
These answers are based on the product details, common RFQ questions, and export order requirements.
Final dimensions, finish, packing, and delivery terms should be confirmed before quotation.
When should I use a double coupler instead of a swivel coupler?
Use a double coupler when two scaffold tubes need to be connected at a fixed 90-degree angle, such as the connection between a standard and a ledger. If the tubes need to meet at another angle, for example in diagonal bracing, a swivel coupler is normally the appropriate fitting. Do not force a double coupler onto an angled connection.
What does EN 74 Class B mean when choosing a double coupler?
EN 74-1 classifies scaffold couplers according to defined structural performance requirements, including resistance and stiffness. A Class B coupler represents a higher performance class than the lower class used for the same general coupler type. If your project specification calls for Class B fittings, the order should be matched to that requirement rather than selected only by coupler weight.
Can a double coupler be used for diagonal scaffold braces?
Only where the tubes actually connect at 90 degrees. Diagonal braces normally meet standards or ledgers at changing angles, so swivel couplers are generally used for those joints. Double couplers are better suited to fixed right-angle structural connections.
Will this double coupler fit standard 48.3 mm scaffold tube?
For EN 74 tube-and-coupler scaffolding, 48.3 mm outside-diameter tube is the key reference size. Product descriptions are sometimes shortened to 48 mm or 48 × 48 mm, but buyers replacing existing couplers should confirm the actual tube outside diameter before ordering rather than relying only on the commercial size name.
How tight should the nuts on a drop forged double coupler be?
The nuts should be tightened to the torque specified for the coupler and scaffold system, not simply tightened as hard as possible. A 50 Nm tightening torque is used for some EN 74 double couplers, but the correct value should be confirmed from the applicable product test certificate, installation instructions, or project specification before erection.
When should a used double coupler be removed from service?
Check used couplers for cracked or deformed forged bodies, damaged threads, bent bolts, nuts that cannot tighten correctly, excessive corrosion, and other visible damage before reuse. A coupler that has been damaged or weakened should not simply be returned to the scaffold because it can still be tightened by hand. It should be properly assessed and repaired or replaced before further use.
