Double, swivel, sleeve and putlog fittings for tube-and-coupler scaffold orders
We supply pressed and drop-forged scaffold couplers in identified connection forms. Double couplers join crossing tubes at a right angle, swivel fittings serve inclined connections, and sleeves join tube ends in line. Our catalog keeps each form, tube-size reference and component mass separate for wholesale component orders.
| Crossing connection | Selected double or swivel two-jaw form |
|---|---|
| In-line connection | External sleeve for the specified tube ends |
| Other listed form | Putlog coupler for its specified attachment role |
| Tube identity | Both mating tube outside diameters and selected fitting family |
| Fastening | Matched captive bolt/nut or other retained closure detail |
| Acceptance | Specified material, finish, coupling class and required test records |
Selected catalog fittings for the stated tube family. Pressed and drop-forged variants retain their own product identities and listed mass ranges.
| Catalog form | Body route | Tube reference (mm) | Listed component mass (kg) |
|---|---|---|---|
| Double/right-angle | Pressed | 48.3 | 0.83–0.87 |
| Swivel | Pressed | 48.3 | 1.02–1.05 |
| External sleeve | Pressed sleeve body | 48.3 | 1.00 |
| Putlog | Pressed | 48.3 | 0.62 |
| Double/right-angle | Drop-forged | 48.3 | 0.97–1.05 |
| Swivel | Drop-forged | 48.3 | 1.12–1.25 |

Factory catalog component/tube/mass references for the selected 48.3 mm family. The actual fitting drawing and required acceptance specification identify saddle fit, fastening, material, finish and any stated class/test requirements.
Two tube saddles are held at the specified right-angle relationship. The selected fitting keeps both tube seats, hinge and fastening arrangement together as one complete double coupler.
A central pivot allows the two saddles to meet an inclined connection. The required angle, bolt access and tube clearances remain part of the selected scaffold joint.
The external sleeve retains the specified two tube ends on one axis. A putlog fitting has its own attachment role and closure geometry; each form follows its identified connection requirement.
EN 74-1 specifies right-angle, swivel, sleeve and parallel couplers working by friction, for temporary works equipment such as scaffolds erected to EN 12811-1 and falsework to EN 12812. Less common coupler types sit in EN 74-2. The adopted edition is named on the order.
A two-jaw fitting is matched to both receiving tubes, including their finished surfaces. Tube diameter, saddle contact and the available closing range are checked together at the selected connection.
The catalog distinguishes formed/pressed bodies from drop-forged fittings. Each selected body retains its own hinge, pivot or saddle geometry, with the specified material and acceptance records.
The selected fastener detail defines closure and the required installation condition. Its tightening requirement follows that actual fitting specification, together with the tool access needed around the assembled tubes.
The connection takeoff separates double, swivel, sleeve and putlog pieces by their required role. We keep those counts and fitting references visible across the wholesale order.
The retained fitting reference and mating tubes identify the replacement saddle and closure arrangement. Different body forms or tube families remain distinct models on the quotation.
Checks identify the saddle diameter and contact shape, hinge/pivot position and required sleeve dimensions for the selected fitting.
The actual bolt/nut set and finished closure are checked against the fitting specification. Required class or mechanical-test records retain their stated product and acceptance scope.
The included closure parts and complete coupler count are reconciled by model. Different forms retain separate carton identification and receiving quantities.
Our quotation identifies the body route, connection form, tube reference and finish for each complete coupler. Included bolts and nuts remain defined within that unit; loose spares have separate counts.
Cartons group double, swivel, sleeve and putlog fittings separately. The agreed carton quantity or mass and protective packing follow the selected product lot.
The packing list links each carton group to its actual fitting reference. Different tube families and fastening details retain separate item lines even where the shapes look similar.
It identifies the catalog’s mating tube outside-diameter reference. The fitting body, saddle, hinge and fastening envelope have their own dimensions on the selected coupler drawing.
The selected fitting specification establishes its permitted tube fit and contact. Our catalog identifies 48.3 and 48.6 mm product families separately; the order retains the actual accepted fitting and tube combination.
Load or slip class follows the specified fitting design and its required test evidence. Component mass supports material and freight comparison alongside those separate acceptance requirements.
A 48.3 mm outside diameter converts to 1.902 in., rounded to three decimals. Keep that actual outside-diameter value with the fitting reference. Nominal pipe size is recorded separately when it forms part of the connected tube specification.
The retained bolt thread, nut form, material and finished-fit requirements identify the part. The selected fitting detail also preserves its bearing and tool-access arrangement.
Yes. A sample request identifies the fitting model and both tube references. The agreed checks can cover saddle seating, closure, hinge or pivot movement and finished surfaces before the production lot is released.
