Heavy-Duty Adjustable Tandem Roller Series (32mm Wheel)

Designed for architectural-grade sliding systems, this Adjustable Tandem Roller Series engineered to deliver exceptional load distribution and effortless sash movement for heavier aluminum sliding doors and oversized windows. Featuring a dual-wheel (tandem) configuration, this assembly spreads the sash weight across a wider track surface, significantly reducing concentrated wear points, preventing track indentation, and ensuring a whisper-quiet glide.

The standout feature of this commercial-grade hardware is its integrated structural height adjustment mechanism. With a vertical calibration tolerance of $\pm$5.2 mm, installation teams can effortlessly square and align heavy door sashes on-site using a standard adjustment screw, eliminating operational drag caused by building settlement or minor frame variances.

Key Features

• Tandem Dual-Wheel Configuration: Features twin $\emptyset$32mm heavy-duty wheels that double the load capacity and tracking stability compared to single-wheel alternatives.
• Precision Height Adjustment: A robust internal screw gearing provides a $\pm$5.2 mm continuous vertical lift adjustment for flawless on-site alignment and balancing.
• Dual Material Grading Options: Available in high-tensile Carbon Steel for standard commercial projects, or premium Grade 304 Stainless Steel (S.S. 304) for marine, coastal, or high-corrosion architectural environments.
• Advanced Surface Passivation: Treated with an industrial color-plated/zinc-plated finish to exceed standard salt-spray test requirements and prevent oxidative wear.
• Engineered Glide Profile: Outfitted with smooth-rolling, low-friction polymeric wheels matching a precision R3.2 tracking radius to ensure zero-rattle, fluid sliding dynamics.
