Plastruct 90517 BFS-10 5/16" Styrene I-Beam – 4-Pack: Scale, Subject & Display Guide

This page is devoted to Plastruct 90517 BFS-10 5/16" Styrene I-Beam – 4-Pack, the exact model building supplies sold under the Plastruct record. The goal is practical identification: what the listing confirms, what remains unverified, and what a buyer or builder should compare before using the item.

Matching the exact listing

• Exact product: Plastruct 90517 BFS-10 5/16" Styrene I-Beam – 4-Pack
• Brand or vendor: Plastruct
• Product type: Model Building Supplies
• SKU or catalog key: PLS90517
• Manufacturer item: 90517
• Quantity wording: 4 -Pack
• Variants reviewed: 1
• Product images indexed: 1

The recorded price at verification was $9.70 before shipping and tax. At least one variant was orderable when the record was checked.

The complete title is meaningful here, not decorative. The quantity wording 4 -Pack should be reconciled with the package photo and option selected. Manufacturer item 90517 is a stronger matching key than a shortened marketplace title. Keep PLS90517 with the product record because abbreviated names often omit the detail that distinguishes one version from another.

The verified description in context

The product page identifies the item this way: “Plastruct 90517 BFS-10 5/16" Styrene I-Beam is a precision model-building component. I-beam stock for scale structural work, bridges and industrial framing. Material: White styrene Quantity: 4 pieces Manufacturer item: 90517 SKU: PLS90517 UPC: 764050905172” That excerpt anchors the guide, while the gallery, SKU and selected variant provide the remaining evidence needed for an exact match.

What matters for this kind of product

For a diecast or scale collectible, the subject name alone is insufficient. Compare body casting, finish, graphics, wheel design, interior, base markings and packaging format. On Plastruct 90517 BFS-10 5/16" Styrene I-Beam – 4-Pack, the exact photo set and SKU PLS90517 are the reference pair; a model with the same vehicle name but a different wheel, road number or package is a different release.

Condition language must also match the format. A loose item is judged from the photographed surfaces and axles, while a packaged item adds card, blister, box and seal condition. A finished custom should be assessed for workmanship and disclosed modifications; a build kit should be assessed for included parts and fitment rather than as a completed collectible.

Second-pass inspection

A good collection note records what is visible and avoids unsupported rarity claims. Write down the exact color wording, graphics, wheel treatment, package condition and any disclosed customization. Market value can change; the product identity should remain reproducible from the record.

Upon arrival, compare the item with the listing images before opening or altering it. Any material discrepancy is easier to document while the original packaging and shipping materials remain intact.

The photographed item is part of the specification

1 product image were available to the catalog at verification. Use them as item-level evidence: zoom in on the SKU, graphics, edges, connectors, part arrangement or package callouts relevant to this model building supplies. Do not substitute a generic manufacturer image when the exact listing supplies a more specific view.

Checks to complete before ordering

• Use the complete name, not a shortened marketplace label.
• Use PLS90517 to prevent a near-match substitution.
• Read the variant and inventory state shown now.
• Confirm technical requirements from the current manufacturer source.
• Keep the receipt and one reference image with the product record.

Cataloging and project notes

Catalog the item under the complete title and PLS90517, then add the date received and the condition actually observed. For a project item, note where it was installed or how it was used. For a collectible, note package and display condition separately.

Retaining the exact identifiers protects the record when product titles or availability later change.

Gift considerations

As a gift, Plastruct 90517 BFS-10 5/16" Styrene I-Beam – 4-Pack is strongest when the recipient already uses this scale, format, subject or product family. Check for duplicates and fit-sensitive details before choosing it solely from the brand name.

Verification worksheet for this listing

Use PLS90517 as the checkpoint for Plastruct 90517 BFS-10 5/16" Styrene I-Beam – 4-Pack. Confirm the vendor name Plastruct, the product type Model Building Supplies, the selected variant and the photographed item before checkout. If a required size, scale, material, interface or included component is absent from the live record, write it down as unresolved and obtain the answer from the current instructions or manufacturer source.

After delivery, add a dated photograph and a brief result note. A builder can record fit, materials and finishing choices; a collector can record package and item condition; a user can record compatibility and care. Those details make the record genuinely product-specific while preventing a later observation from being confused with a factory specification.
