SPAN 400 Scaffold Systems and Replacement Parts

A configurable scaffold family, not one fixed tower

SPAN 400 is best understood as a structured family of components that can support different scaffold arrangements after the required configuration has been established. The source document organizes the family by functional product groups instead of presenting a single package. That organization matters when a customer is planning a new tower, identifying a replacement part, comparing single-width and double-width formats, or reviewing whether an existing fleet contains the correct components.

Single-width and double-width designations describe important geometry, but width alone does not establish interchangeability. Products that appear similar can use different spigot directions, rung patterns, brace lengths, connection details, platform types, or assembly relationships. Exact-number identification is therefore carried throughout this catalog architecture. Every verified row has a canonical record, and every uncertain row remains visibly separated for manual review.

Frames, bases, and vertical configuration

The frame architecture separates standard frames, base frames, ladder frames, guardrail frames, V-X frames, and V-X ladder frames. It also preserves the distinction between versions supplied with adjustable legs and versions supplied without them. Standard three-rung and five-rung frames have source-supported orientation language: the drawing permits base-frame orientation with spigots up or extension-frame orientation with spigots down. That statement is product-specific and does not authorize use in every possible tower.

V-X folding bases form another distinct branch. The source lists single-width and double-width assemblies in 6, 8, and 10 foot nominal lengths, along with versions with legs, without legs, and ladder-type assemblies. Where the source says four 0.4 m adjustable legs, Part 9517-01, are included, that relationship is retained. Castors, platforms, toe boards, guardrails, ladders, and outriggers remain separately paired components unless a written quote states otherwise.

Platforms, access, and edge components

Standard and trapdoor platforms are listed in four nominal lengths. A standard platform and a trapdoor platform of the same length remain separate exact-number products because their access function and construction differ. Trapdoor products are connected contextually to ladder and ladder-frame pathways, while the page still stops short of prescribing an access configuration.

The toe-board architecture includes four-piece wooden sets, individual side boards, single-width and double-width end boards, and one-piece hinged folding products. This separation supports both complete-set inquiries and exact replacement-part searches. Set pages and individual components share length and width context without suggesting that any similarly sized board can be substituted.

Bracing, guardrails, and stabilization

Horizontal and diagonal braces have their own metric and imperial dimensions, weights, and—in several rows—ring-color identifiers. Ring color can assist identification, but color alone is not sufficient to confirm compatibility. Guardrail bracing frames also include standard, R-suffix, and additional-geometry variants. Matching nominal length does not erase those geometry or suffix differences.

Guardrail records are separated by width, spigot direction, special-system designation, and extension-combination geometry. These pages provide part-number and dimensional context, not a complete fall-protection design. Outriggers are similarly presented as three individual products: fixed, telescopic, and heavy-duty. Their drawings do not establish tower-height permissions or substitute for configuration-specific stabilization requirements.

Mobility, leveling, and access components

The adjustable-leg group includes 0.4 m, 0.6 m, and 0.8 m products. The source also identifies an integral steel leg and 200 mm caster assembly as its own exact-number product, separate from standalone legs and standalone castors. Caster pages retain individual component load values only with a clear warning that those figures are not complete-tower capacities.

The six-step inclined ladder, base ladder frames, standard ladder frames, and V-X ladder frames remain distinct products. Their names describe different component forms and should not be treated as replacements for one another. A useful quote request identifies the current platform, access opening, frame width, labels, attachment points, and surrounding assembly.

How to use this catalog

Begin with the visible part number whenever possible. Search the component hub using the complete code, including suffixes. Then confirm the product family, width designation, nominal length, source-supported dimensions, weight, connection style, and installed orientation. Add photographs of the complete part and both connection ends. For assemblies, distinguish expressly included components from commonly paired products.

Pricing, stock, freight, lead time, and current availability are intentionally not invented. Submit the exact part number, quantity, shipping ZIP code, required date, existing scaffold details, and application notes to Upright Scaffold. Website summaries support identification and commercial inquiry; they do not replace the complete applicable manual, site-specific engineering, employer procedures, competent-person inspection, qualified-person review, or applicable requirements.
