Drawing-based telescopic props, adjustment parts and bearing ends
Our adjustable prop range covers telescopic assemblies and replacement tubes, nuts, pins, heads and bases made to identified drawings. The published 60/48 mm configuration adjusts from 2,000 to 3,500 mm. Load-rated selection requires evidence for the complete assembly at its working height; this page provides dimensions and component options.
Complete props combine the inner and outer tubes, adjustment nut, retaining pin and selected bearing ends. The same component families can be quoted as separate replacement parts.

| Tube components | Identified inner or outer tube | Tube OD, wall, prepared ends and holes |
| Adjustment parts | Specified handled nut, cup nut, sleeve or pin | Mating thread, pin and tube-family detail |
| Head and base parts | Drawn flat plates or U-head arrangement | Bearing face, attachment and supplied configuration |

Our supply covers the specified prop steel and adjustment parts. Formwork panels, beams, bracing and the installed shoring layout belong to the project’s temporary-works package.
The published 60/48 mm assembly uses 2.0 mm walls and adjusts from 2,000 to 3,500 mm. The 56/48 cup-nut and 48/40 families use their own assembly drawings. These dimensions support fabrication and fit selection; they are not working-load ratings.
Collapsed length describes the shortest assembled prop. Working length describes the required support height between its bearing faces. The permitted extended limit belongs to that same assembly, including its engagement and adjustment limits. Both ends of the usable range matter: a prop that extends high enough can still be too long for a lower position.
Flat plates and U-heads change the bearing faces and assembled support height. The height on the assembly drawing includes the selected head and base.

Select the required height and end arrangement before matching replacement components. A load-rated order also needs the model-specific record for that extension and bearing condition.
Inner and outer tubes, end plates, pins and adjustment pieces retain their own specified materials and dimensions on the assembly list.
A handled nut and a cup-style adjustment assembly use their respective mating threaded regions and bearing details. The selected nut form stays with its sleeve or outer tube and pin arrangement. A similar-looking nut, or a shared inner-tube diameter, does not establish the missing thread and contact dimensions.
A flat end plate and a U-head meet the formwork at different surfaces. Plate size, holes, attachment and orientation follow the end detail; a U-head also has a defined opening and bearing area for the scheduled beam. The shoring arrangement determines the contact and alignment required at the top and base.
Painted and galvanized prop options are quoted with their component coverage. The finish schedule identifies the tubes, welded end plates and adjustment pieces, together with any required color and inspection basis. This keeps the finish on a complete assembly distinguishable from the finish on a separately supplied spare.
The inner tube must move through its mating outer tube, and the nut must engage its specified threaded region. Finish checks therefore include sliding surfaces, pin openings, threads and bearing contacts. Coating buildup or damaged surfaces are assessed against the required fit of that assembly before packing.
The inner tube’s hole positions provide the coarse height selections. Hole pitch, pin diameter, pin form and the bearing detail come from the component drawing. The prepared hole series uses the tube’s stated reference, keeping the pin position aligned with the adjustment region rather than locating each opening from an unrelated end measurement.
The nut provides the smaller length adjustment within the specified threaded region. Thread form, pitch, engagement and nut travel belong to the selected assembly. Our preparation uses those defined features rather than interpreting an abbreviated tube-and-sleeve description as a complete screw specification.
Fabrication fixtures locate each end plate or head from the tube reference. The weld detail fixes the attachment, while plate orientation and bearing-face alignment remain measurable assembly features. Pin-retaining provisions are prepared to their own detail so a loose retention part is not mistaken for the main bearing pin.
A distributor can order several prop families by their item references and quantities. The selected range follows the heights and end arrangements in its sales program. Complete props and replenishment spares keep separate purchase lines, giving the distributor a defined product range rather than an unspecified mixed-tonnage lot.
Inventory buyers match new assemblies to the family already held in the yard. Similar colors or tube diameters can conceal a different nut, pin or head arrangement. The inventory reference preserves that distinction, while the operator retains responsibility for inspecting and managing the existing fleet.
Use the repeated-cycle steel prop specification guide to compare complete models at the required working heights.
Contractor orders follow the released temporary-works schedule and the working heights assigned to it. Props at different support positions can require different configurations even on one floor. The purchased quantities follow that schedule; permanent machine frames, building columns and scaffold access members remain separate product families.
Checks cover tube diameter, wall, length and pin-hole positions, followed by sliding movement, pin retention and nut travel on the assembled prop.
End checks cover plate geometry, alignment and specified weld inspection. Part and lot marks connect the completed assembly to its material and finish records.
This range has no published model-by-extension load chart. A load-rated selection must use a record identifying the complete prop, working extension, end conditions and test or calculation basis. The component dimensions shown above cannot establish that rating.
OSHA 1926.703 requires shoring to support the anticipated loads and addresses bearing contacts and site inspection. The installed layout and condition of the props must satisfy the project’s shoring design.
Complete props are priced with the specified nut, pin, head and base. Replacement parts have separate counts, so a replenishment order can buy only the needed components.
Prop bundles are supported and restrained in their agreed transport condition. The packing arrangement protects projecting handles, threaded regions and end plates rather than using those features as strap contact points. Assembled length and the bundle envelope determine the packing space; maximum working extension is a different dimension.
Loose pins, nuts and other spares are grouped by mating prop family and part number for receiving.
Yes. A component drawing or mating-part dimensions identify the replacement. A shared tube diameter alone does not establish the correct pin or thread.
Use a load record for the complete prop at the required height and end conditions. This page does not publish a rated model range; tube dimensions and maximum extension alone are insufficient for that selection.
No. The complete used assembly needs inspection by the responsible operator. OSHA 1926.703 prohibits use of shoring whose damage reduces its required strength.
Yes. Each end arrangement has its own assembly drawing and quantity, including the corresponding bearing-face height.
Start with the assembly or parts you need, the working-height range, quantities and delivery destination. Include any available drawings and known head, base and finish requirements. If a working-load rating is required, tell us the load and extension so we can assess the evidence needed before confirming the supply scope.
