ESANG through-post hardware is used when stainless steel cable passes through railing posts instead of attaching only to the outside surface. These components help guide, protect, align, or finish cable pass-through points in cable railing systems.
Esta categoría incluye Through Post Cable Hardware, Cable Pass-Through Fittings, y Corner Post Cable Hardware.
For contractors, distributors, fabricators, and project buyers, through-post hardware selection should consider post shape, post hole size, cable diameter, cable direction, terminal condition, corner routing, material grade, surface finish, and installation environment. ESANG can supply and manufacture through-post cable hardware according to drawings, post dimensions, cable size, hole layout, material grade, finish requirements, and installation conditions.
| Opción de hardware | Ideal para | Preguntas clave para la selección |
|---|---|---|
| Through Post Cable Hardware | Cable runs passing through stainless steel posts in straight or repeated railing layouts | What post shape, cable diameter, hole size, and pass-through detail are required? |
| Cable Pass-Through Fittings | Protecting, aligning, or finishing cable holes through intermediate posts | What fitting style, post wall thickness, hole diameter, and cable direction should be matched? |
| Corner Post Cable Hardware | Cable systems where cable changes direction at corner posts or angled railing runs | What corner angle, cable routing path, tensioning plan, and post design are required? |
Through-post hardware should be selected according to the role of the post. An intermediate post, terminal post, and corner post may all have cable holes, but the cable direction and hardware function can be different.
| Estado del proyecto | Dirección recomendada | Por qué es importante |
|---|---|---|
| The cable passes straight through intermediate posts | Use through post cable hardware or cable pass-through fittings | Pass-through fittings help protect cable and improve alignment through the post. |
| El cable cambia de dirección en una esquina | Utiliza los accesorios para cables de los postes de esquina o sigue las instrucciones de tendido específicas del proyecto | Corner routing changes cable angle, tension, friction, and hole alignment. |
| The cable terminates at a post | Use terminal hardware and cable end fittings rather than only pass-through fittings | Termination and pass-through functions should not be confused. |
| The post has pre-drilled cable holes | Match fittings to hole diameter, post wall thickness, and cable size | Incorrect hole or fitting size can affect installation appearance and cable movement. |
| The system uses square or rectangular posts | Confirm hole position, face orientation, and fitting shape | Flat post faces make alignment important across the cable run. |
| The system uses round posts | Confirm cable hole angle and fitting shape for curved surfaces | Round post geometry changes how the fitting sits and how the cable exits the post. |
Cable pass-through details depend on post position. A cable may pass through an intermediate post, terminate at a terminal post, or change direction at a corner post.
| Posición de salida | Through-post role | Aspectos generales a tener en cuenta |
|---|---|---|
| Publicación intermedia | Allows cable to pass through while maintaining spacing and alignment | Hole spacing, fitting protection, cable direction, and post wall thickness |
| Poste terminal | Often anchors, tensions, or terminates the cable rather than simply passing it through | End fittings, tensioners, post strength, and finished cable length |
| Pilar de esquina | Changes cable direction and may require special routing or angled fittings | Corner angle, cable friction, tensioning plan, hole alignment, and post orientation |
| Stair post | Guides cable through angled stair runs | Stair pitch, cable angle, hole layout, and fitting alignment |
Through-post cable systems require accurate post hole layout. Hole position, spacing, and direction should be confirmed before production, especially for custom posts, stair runs, or corner conditions.
| Layout item | Qué hay que confirmar | Por qué es importante |
|---|---|---|
| Cable diameter | Cable size and compatible pass-through fitting | The fitting must protect and guide the correct cable size. |
| Hole diameter | Drilled hole size, fitting fit, and tolerance | Incorrect holes can create loose fittings or difficult installation. |
| Hole spacing | Vertical spacing between cable runs | Spacing affects appearance, opening control, and cable layout. |
| Post wall thickness | Thickness of round, square, rectangular, or custom post | Fitting design and installation method should match the post wall. |
| Dirección del cable | Straight, angled, stair, or corner routing | Cable direction affects hole angle and fitting position. |
| Fitting finish | Visible surface finish around each pass-through point | Pass-through hardware should match the railing finish where visible. |

For non-standard cable railing projects, customers can provide drawings, post shape, post dimensions, cable diameter, hole layout, cable direction, corner condition, finish requirements, and project environment. ESANG can review the requirements and manufacture through-post hardware to match the project specification where feasible.
Through-post hardware should be selected together with cable fittings, tensioners, end fittings, posts, and spacer bars. It is one part of the complete cable routing system.
Many through-post cable hardware projects are customized according to post shape, cable diameter, hole layout, cable routing direction, and installation environment. ESANG can support custom through post cable hardware, cable pass-through fittings, corner post cable hardware, drilled post layouts, and related stainless steel cable routing components.
When a project has standard-oriented requirements related to guardrail height, cable spacing, opening limitations, material grade, corrosion resistance, or installation method, customers should provide the required drawings and specifications. ESANG can manufacture through-post hardware to match those provided details, while final compliance depends on the complete installed system, structural design, installation method, and applicable local code.
Through-post hardware should be planned before posts are drilled or manufactured. Cable hole layout, cable direction, post spacing, and fitting type should be confirmed together.
For cable railing projects on decks, balconies, stairs, terraces, and public-access areas, the complete installed system should be reviewed by the project designer, engineer, contractor, or local authority. ESANG can manufacture through-post hardware to match provided requirements, but final compliance depends on the full assembly and site conditions.
Through-post hardware is commonly used where cable passes through intermediate posts along straight railing runs. Hole spacing, cable alignment, and fitting finish should be coordinated before production.
Corner post cable hardware is used when cable changes direction at balcony, deck, or stair corners. Corner angle, cable routing, and tensioning strategy should be reviewed together.
Stair cable railing projects may require angled through-post holes or special pass-through fittings. Stair pitch, post location, and cable direction should be confirmed before drilling or fabrication.
Deck and balcony cable railings often use through-post hardware with stainless steel posts to create clean horizontal cable lines. Cable diameter, post spacing, and terminal conditions should be planned early.
Los entornos al aire libre, junto a piscinas, costeros y húmedos requieren prestar mayor atención a la resistencia a la corrosión, la limpieza y la calidad del material. Para condiciones de exposición más exigentes, se puede considerar el uso de acero inoxidable 316 o 316L.
Through-post cable hardware is used when cable passes through railing posts. It may guide, protect, align, or finish the cable hole where the cable travels through intermediate, terminal, stair, or corner posts.
Cable pass-through fittings are used to protect and finish the cable hole in a post. They help improve cable alignment and reduce direct contact between the cable and raw post hole edges.
Corner post cable hardware should be used when cable changes direction at a railing corner. Corner routing affects cable tension, hole angle, and fitting layout, so it should be planned before post fabrication.
Through-post fittings guide cable through a post. Cable end fittings terminate the cable at the end of a run or connection point. Some terminal posts may require both routing and termination hardware, depending on the layout.

Yes. Through-post hardware can be designed for round, square, rectangular, or custom stainless steel posts. Hole position, post wall thickness, cable direction, and fitting shape should be confirmed before production.
El acero inoxidable 304 se utiliza habitualmente en interiores y entornos secos. El acero inoxidable 316 suele ser la opción preferida para entornos exteriores, costeros, junto a piscinas, húmedos o con mayor riesgo de corrosión. El tipo definitivo debe seleccionarse en función de la exposición del proyecto y de las especificaciones.
Useful information includes cable diameter, post shape, post size, post wall thickness, hole diameter, hole spacing, cable direction, terminal or corner condition, material grade, finish, quantity, and drawings.
Yes. Stair cable railings may use through-post hardware, but hole angle, stair pitch, cable direction, and post position must be confirmed carefully before fabrication.
Para la limpieza habitual se suele utilizar un detergente suave, agua limpia y un paño suave. Evite los productos de limpieza a base de cloro, la lana de acero y los utensilios abrasivos. Las instalaciones al aire libre, junto a la piscina y en la costa deben limpiarse con mayor frecuencia para reducir la contaminación de la superficie y mantener su aspecto.
Especifica el tratamiento en función del estado de la pieza, el proceso de fabricación y la exposición, en lugar de aplicar una única especificación genérica de pasivación a todos los componentes.
Limpia los terminales de los cables, las abrazaderas de cristal, los elementos de fijación y las hendiduras sin que queden restos de productos químicos ni se dañen los acabados pulidos y cepillados.
Las manchas de té se deben a partículas incrustadas, al cambio de color por calor, a la transferencia de partículas abrasivas y a los residuos atrapados en las líneas de acabado o en las grietas.
El decapado elimina las incrustaciones y las capas superficiales alteradas; la pasivación se ocupa del estado de la superficie tras la limpieza, con diferentes controles y riesgos.
El mantenimiento debe centrarse en la exposición, la acumulación de sal, las grietas, la combinación de metales diferentes, el estado de los elementos de fijación y el aspecto del acabado.
Elimine el polvo de esmerilado, los residuos de soldadura, los depósitos de cemento y la contaminación por acero al carbono antes de la entrega para evitar manchas que se puedan prevenir.
