Ringlock and frame components for bulk scaffold orders
H-frame scaffolding is available in four catalog sizes; ringlock supply includes vertical standards, ledgers and diagonal braces. Choose individual components or a counted kit. Frame locks and ringlock rosette connections use separate part drawings, with matching base, platform and access parts listed for each family.
Frame scaffolds use paired frames and cross braces. Ringlock scaffolds use standards, ledgers and diagonals connected at rosettes. Platforms, base parts and access components complete the selected assembly.
| Component group | Supplied items | Matching connection |
|---|---|---|
| Frame scaffolding | H, walk-through or ladder frames; cross braces | Frame drawing and its brace/lock arrangement |
| Ringlock scaffolding | Standards, horizontal ledgers and diagonal braces | Member drawing and rosette/head connection family |
| Joining and base parts | Specified joining pins, locking fittings and base-jack items | Mating socket, pin or thread detail |
| Platforms and access parts | Scheduled steel platforms and stair components | Support, hook and attachment details |

Individual parts and complete kits are separate purchase options. A kit includes only the members and accessories listed in its contents; platforms and stair parts are specified explicitly.
H-frames use a 1,219 mm catalog width with four height choices. Ringlock vertical standards have a 48.3 mm tube OD and nominal lengths from 0.5 to 3.0 m. Each family uses its own connection drawings.
Find the frame height for your component schedule.
| Frame selection | Catalog width (mm) | Catalog height (mm) | Connection selection |
|---|---|---|---|
| H-frame 1219 × 914 | 1,219 | 914 | Frame locks, pins and matching braces |
| H-frame 1219 × 1524 | 1,219 | 1,524 | Frame locks, pins and matching braces |
| H-frame 1219 × 1700 | 1,219 | 1,700 | Frame locks, pins and matching braces |
| H-frame 1219 × 1930 | 1,219 | 1,930 | Frame locks, pins and matching braces |

The frame drawing locates the width and height datums, brace locks and joining pins. These details identify the matching braces and accessories.
The lengths below are the published vertical-standard selections. Tube wall, rosette positions, spigot and retaining-pin details follow the selected standard drawing. Ledgers and diagonals are supplied to their member drawings; bay dimensions do not substitute for finished component lengths.
| Nominal standard length (m) | Tube outside diameter (mm) |
|---|---|
| 0.5 | 48.3 |
| 1.0 | 48.3 |
| 1.5 | 48.3 |
| 2.0 | 48.3 |
| 2.5 | 48.3 |
| 3.0 | 48.3 |
A cross-brace end engages the frame’s locking point; a joining pin connects the leg sections. Hole-ended and notched braces retain their own mating locks. Leg sockets, pin shoulders and retaining holes follow the frame detail, even where two frames share the same height or outside width.
The standard’s rosette, ledger head, diagonal head and wedge form the ringlock connection. Their shape, seating and spacing belong to the selected family. A 48.3 mm tube diameter alone does not identify that joint; the spigot and retaining pin also need their own matching detail.
Tube walls, connection heads, frames and loose pins use the materials specified in their component drawings. The grade for a standard does not automatically specify the material of its ledger head or retaining pin.
Painted, pre-galvanized and after-fabrication hot-dip galvanized components are quoted to the selected part specification. The finish description identifies the tube, welded joints and connection pieces it covers. Painted items also retain their color and coating requirements, keeping repeat batches identifiable.
Wedges, lock mechanisms, joining sockets and base-jack threads are checked in their finished condition. Coating buildup, blocked holes or damaged contact surfaces affect assembly, so their acceptance follows the component detail. Specified coating repairs retain that same fit and finish basis.
Overall frame width and leg-center spacing are different measurements. Rungs, brace locks and platform interfaces are located from the drawing’s stated datums.
Bay width and lift height locate the ringlock nodes. Ledger and diagonal lengths also depend on their heads and end offsets, so fabrication uses the finished member dimensions.
Frame fixtures locate the leg tubes, rungs and brace locks from the frame datums. Ringlock fabrication locates the rosettes and prepared member heads from their own connection references. The shop detail controls those positions and weld arrangements, keeping layout dimensions separate from the finished piece length.
Wholesale batches can combine frames or standards with their matching braces, ledgers and pins. Component-only orders retain their own quantities, with frame-lock and ringlock-head variants listed separately.
A fleet top-up starts with the actual component family already held in the yard. Different frame locks or ringlock head revisions stay on separate lines, rather than being grouped under a broad scaffold description. This is a parts-supply order; fleet inspection and release for use remain with its operator.
Before a fleet top-up, review the reusable scaffolding purchasing checks for component identity, compatibility and counted kits.
Project orders follow the scaffold layout and its component takeoff. The schedule identifies the access routes, working levels and associated platform, stair and base items being purchased. Scaffold access parts remain separate from concrete-formwork shoring props and permanent structural steel.
Checks cover frame dimensions, member lengths, lock movement, pin retention and mating-part seating. Fit checks use the selected parts in their specified finish condition.
Required weld and coating checks follow the component inspection plan. Part marks link material, connection and finish records to the drawing revision and supplied lot.
OSHA 1926.451 assigns scaffold design to a qualified person and requires the assembled scaffold to follow that design. Mixed-manufacturer parts need force-free fit and maintained structural integrity. A component’s dimensions or factory inspection do not establish a universal load rating or authorize a mixed assembly.
The order identifies the component drawings and required material, finish and inspection records. Any system evidence must cover the actual assembled configuration.
Scaffold prices identify each frame, member, accessory or defined kit and its piece count. Packing and shipment terms accompany the selected finish and component mix.
Frames and ringlock members are bundled separately by part and finish. Supports protect sockets, projections and platform hooks; small pins and lock fittings are boxed by item.
Kit labels connect the accessory cartons to their member bundles. Loose spares have separate counts, allowing the receiving team to check both against the contents list.
Yes. A part drawing or a measured mating-frame detail identifies the standalone replacement.
It can show the lock style, end pattern or rosette type. A drawing or measurements are still needed for scale, wall thickness and hidden socket geometry.
No. Platforms, stair flights, landings and rail pieces are separate components. A kit includes the specific items shown in its contents list.
Start with the frame or ringlock parts and quantities you need, plus any available drawings, part references or photos. Include the finish and delivery destination if known. We confirm connection details before manufacture and quote the parts, accessories, kit contents and packing separately.
