Top Anti-Sway Guides, Heavy-Duty Rollers & Baffled Drainage Control

BC-S120 integrates adjustable top anti-sway guides, tandem load-distribution rollers, stainless-steel rails, and gravity-operated wind baffles to deliver stable, quiet sliding performance, 160kg+ sash capacity, and reliable stormwater control through more than 100,000 operating cycles.

BC-S120 adjustable top anti-sway guide wheel mechanism

Top Anti-Sway Guide Wheel Mechanism

Adjustable polymer guide wheels close the upper-track clearance to stabilize the sash, assist smooth travel, and suppress wind rattle or derailment risk on exposed high-rise facades.

BC-S120 heavy-duty tandem bottom roller running on stainless-steel rail

Heavy-Duty Tandem Rollers & Stainless Rails

Dual-row composite wear-resistant rollers distribute 160kg+ sash loads across stainless-steel running rails for low-effort travel, long service life, and dependable anti-derailment control.

BC-S120 gravity-operated wind baffle over stepped drainage outlet

Gravity-Flap Windproof Drainage Baffles

Independent one-way baffles let runoff discharge by gravity, then close automatically under reverse wind pressure to block stormwater backflow into the track and interior floor zone.

BC-S120 flush touch latch crescent lock and keyed sliding-window handle options

Multi-Brand Minimalist Lockset Compatibility

The concealed transmission system supports flush touch latches, embedded crescent locks, and keyed interlocking handles, allowing security and appearance to be coordinated with each project specification.

BC-S120 Architectural High-Weatherability Surface Finishes & Color Palette

BC-S120 profiles are finished on automated vertical coating lines using AkzoNobel fluorocarbon coatings and TIGER weather-resistant powders, passing 1000-hour neutral salt-spray testing for durable adhesion, corrosion resistance, and color retention under intense UV and marine exposure.
