Frequently Asked Questions

What is the S29 two-screw type conduit fitting?

The S29 series is a two-screw type conduit fitting designed specifically for flat oval-profile flexible metal conduits, particularly the XPO series. Manufactured from zinc alloy with a slightly flat outline, it provides reliable mechanical connection while maintaining a compact profile ideal for office automation (OA) wiring systems in furniture and partitions.

What does "two-screw type" mean?

Two-screw type means the fitting is secured to the conduit by tightening two set screws that clamp a cover over the conduit, creating a firm mechanical connection. This design provides secure holding without deformation of the conduit and allows for quick installation and removal when needed.

What conduits is S29 compatible with?

S29 is designed and mated with the XPO flexible oval steel conduit series and also compatible with PRWG galvanized steel round conduit. The fitting accommodates both oval and round conduit profiles, providing versatile connection options for different installation requirements.

What sizes are available?

S29 series is available in two sizes: S292-1/2" (for 1/2" nominal conduit) and S292-5/8" (for 5/8" nominal conduit). Both sizes are packaged in boxes of 300 pieces, ideal for high-volume office furniture and OA wiring projects.

What is the material composition?

S29 is manufactured from zinc alloy with chromate surface finish, providing good corrosion resistance and a professional appearance. The zinc alloy construction ensures reasonable strength while maintaining lightweight characteristics suitable for furniture applications.

What is the operating temperature range?

S29 operates reliably between -50℃ and +200℃, covering diverse environmental conditions from cold storage to moderately heated areas. This temperature range is appropriate for most office furniture and commercial automation installations.

What is the IP rating?

S29 has an IP40 rating, providing protection against solid objects larger than 1mm and splash water from any direction. This rating is appropriate for indoor office environments and protected locations in commercial buildings.

Why is the flat outline design important?

The slightly flat outline of the S29 fitting body is specifically designed for office furniture and OA wiring systems where space is limited and aesthetic appearance is important. The flat profile reduces the bulge created by the fitting, allowing it to fit better in confined furniture compartments and wire ducts.

Is S29 RoHS compliant?

Yes, S29 series is fully RoHS compliant, ensuring no hazardous substances are used in manufacturing and meeting international environmental regulations. This is important for office furniture destined for environmentally-conscious markets.

What certifications does S29 hold?

S29 series holds CE certification, ensuring compliance with European safety and quality standards. This certification allows for use throughout the European Union and other markets requiring CE compliance.

What are typical applications?

S29 is ideal for office furniture wiring, workstation OA (Office Automation) systems, modular office partitions, electrical connections in desks and cabinets, commercial telecommunications systems, and any application requiring compact, space-saving conduit connections in furniture.

How is S29 installed on the conduit?

Installation is straightforward: slide the fitting over the conduit end, position the cover, and tighten the two set screws evenly to secure. The two screws create a firm clamping action that holds the conduit without damaging it. Avoid over-tightening to prevent conduit deformation.

What is the packaging quantity?

S29 is packaged in boxes of 300 pieces per size, with each box weighing approximately 16kg. This high-quantity packaging is ideal for furniture manufacturers and large-scale OA wiring projects requiring bulk quantities of fittings.

How does S29 compare to other fitting types?

S29 two-screw type offers advantages over set-screw types in compact applications. Its flat outline design specifically suits office furniture, while the two-screw clamping provides secure holding without distorting the conduit. Set-screw types (S11-S24) are more versatile for various conduit sizes and applications.

Are other surface finishes available?

The standard surface finish is chromate for corrosion resistance and appearance. Other treatments (such as nickel plating, zinc plating, or painted finishes) are available upon consultation with our engineering team for specific project requirements.

Can S29 be used with both XPO and PRWG conduit?

Yes, while S29 is specifically designed for XPO oval conduit, it is also compatible with PRWG round galvanized steel conduit. This dual compatibility provides flexibility in choosing conduit types for your office furniture projects.

What tools are needed for installation?

Installation requires only a simple screwdriver (typically #2 Phillips or equivalent) to tighten the two set screws. No special tools or equipment are needed, making installation straightforward for field installers with minimal training.

Is grounding capability available?

When properly installed, the zinc alloy body and secure connection to the metal conduit provide continuity for grounding purposes. Always verify with local electrical codes whether your application requires additional grounding conductors or bonding provisions.

Why is S29 popular for office furniture?

S29 is popular for office furniture because: the flat outline minimizes visual bulge in furniture design, two-screw connection provides secure holding in confined spaces, compact size allows integration in thin-wall furniture compartments, CE certification ensures code compliance, and bulk packaging (300/box) reduces per-unit costs for furniture manufacturers.

Can custom specifications be ordered?

Yes, custom configurations are available for special furniture projects including alternative surface finishes, custom packaging quantities, and project-specific requirements. Contact our sales team at info@flexible86.com or +86-563-6636999 for bulk orders and custom specifications.
