4-8 Registration Eye Clamp
Combined ring-and-clamp fitting that grips a wire and provides an ear in one compact node.
Specifications
| Model | 4-8 |
|---|---|
| Drawing No. | 4-8 |
| Standard | TB/T 2075.4-2024 — Part 4: Non-limit-type positioning devices |
| Installation | Clamps wire and tube together, providing a connection ear in one node |
The 4-8 registration eye clamp integrates a clamp ring and a wire clamp in one body: bolted around a tube it provides the connection ear, and its clamp groove simultaneously grips a contact wire or messenger wire. One part does the work of two, simplifying the connection node and reducing the part count.
The clamp groove curvature matches the wire section, so the grip is firm without groove damage, and the ear accepts the standard rope and positioning fittings. It serves both positioning structures and anchor-branch constructions.
Design Features
- Ring and wire clamp integrated — compact, low part count
- Groove curvature matched to the wire — firm grip, no damage
- Ear accepts standard rope and positioning fittings
- Anti-corrosion finish for long-term outdoor service
The product is manufactured under CRCC railway product certification and an ISO 9001 quality management system, with incoming material inspection, in-process control on critical operations and batch-by-batch final inspection before delivery.
Henan Chuangwit Railway Equipment Co., Ltd. supplies this locator with selection calculations, matched fittings and site technical guidance for traction power projects. It is a clamp ring and a wire clamp in one body: the ring bolts to the tube, the groove grips the wire, and the ear takes rope or positioning fittings — all in a single node. Contact wire or messenger wire of the matched cross-section; confirm your wire section when ordering so the groove profile suits it. Wire-to-tube nodes in positioning structures and anchor-branch constructions where a separate ring plus a separate clamp would otherwise be needed. Yes — the ear hole follows the standard interface of the positioning-family ropes and fittings.Frequently Asked Questions
