The QO002 series through-hole flat surface brackets are robust anchoring components designed for securing larger-diameter cross bars to flat mounting surfaces in handrail and balustrade assemblies. Constructed from premium stainless steel — AISI316 for exterior and coastal-grade durability, with AISI304 optional for interior installations — these brackets accommodate 14mm and 16mm cross bar diameters with a uniform 25mm holder height. The through-hole architecture allows the cross bar to pass cleanly through the bracket body, creating a flush, professional appearance. Eight model variants provide mounting options for flat surfaces as well as round tubes at 33.7mm, 42.4mm, and 48.3mm diameters. Supplied in satin or mirror finish, the QO002 series offers heavy-duty support for larger cross bar spans in demanding architectural environments.

• Large-diameter cross bar support — engineered for 14mm and 16mm bars serving longer spans and heavier loads.
• Through-hole passage design — enables continuous cross bar routing through the bracket for seamless visual flow.
• Uniform 25mm holder height — consistent installation dimensions across all eight model variants.
• Flat surface optimization — specifically profiled for secure mounting on flat posts, walls, and panel surfaces.
• Eight-model coverage — two bar diameters x four mounting options for comprehensive project adaptability.
• Dual material selection — AISI316 for marine and harsh outdoor settings; AISI304 for protected interiors.
• Two finish choices — satin brushed or mirror polished to harmonize with surrounding architectural finishes.
• ISO9001 manufacturing — MTC-certified quality with complimentary pre-order sample evaluation.

Targeted for flat-surface cross bar anchoring in handrail and balustrade systems — staircases, balcony perimeters, deck enclosures, terrace boundaries, and commercial building safety railings. The 14-16mm bar capacity makes this series particularly suitable for longer cross bar runs where increased bar diameter ensures reduced deflection and enhanced structural stiffness.

Each bracket is individually enclosed in protective film, packed into reinforced export cartons, and palletized for transit integrity. Bespoke packaging configurations accommodated on request. Manufacturing lead times are volume-dependent and confirmed at order placement; punctual shipment is contractually guaranteed. Every dispatch includes MTC and ISO9001 certification documentation.

• Larger bar capacity — 14-16mm support for extended cross bar spans with reduced deflection.
• Through-hole continuity — clean, uninterrupted bar passage through the bracket body.
• Eight model variants — two bar sizes x four mounting types for maximum design flexibility.
• Marine-grade option — AISI316 for waterfront, coastal, and high-humidity installations.
• Pre-purchase sampling — complimentary sample program for hands-on evaluation.
• Documented quality — ISO9001 production with full material test certification.
• Direct-from-manufacturer pricing — competitive rates with scalable volume incentives.
