This rectangular drive box serves as the core drive and locking component of casement door and window systems. Specifically designed for aluminum alloy casement windows and doors, it works in conjunction with the handle's square shaft to drive the transmission rod, enabling multi-point synchronized locking. With its compact structure and precise, stable operation, it is a critical component of the entire door & window hardware locking system.
High-Strength Alloy Housing
The main body is made of high-density alloy and formed through one-piece die-casting, resulting in a solid and compact structure with excellent torsion resistance. It withstands the repeated opening, closing, and twisting forces from the handle over the long term without deformation or cracking.
The surface features a black anti-corrosion treatment that blocks moisture and prevents oxidation, making it suitable for the sealed, humid environment inside the profile cavity and ensuring it remains rust-free and free of jamming even after prolonged use.
Reinforced metal mounting flanges extend from both sides, ensuring precise positioning and strong load-bearing capacity. Once installed, the assembly remains stable with no play, maintaining transmission precision over time.
Precision Engineering & Performance
The internal precision transmission components mesh tightly, ensuring uniform and smooth torque transmission. The operation feels firm with no backlash, withstanding high-frequency repetitive use and ensuring a long service life.
Standard Specifications & Easy Installation
Standard-spec interfaces ensure easy installation and strong compatibility. A standard square drive hole is located in the center, compatible with industry-standard square handle shafts, allowing direct pairing with mainstream handles for casement doors and windows on the market.
The elongated profile fits standard grooves in conventional door and window profiles, ensuring a tight, flush fit during embedded installation without the need for additional cutting or slotting of the profiles.
The installation flanges feature pre-drilled standard screw holes for precise alignment; fastening can be quickly completed using the included screws. This enables efficient and convenient batch assembly at door and window factories, effectively reducing labor costs.
Enhanced Performance Features
The transmission stroke is precisely matched to standard locking point specifications, providing clear feedback when fully locked. When used with multi-point transmission rods, it ensures uniform compression across the entire door or window, enhancing sealing and sound insulation performance.
Applications & Compatibility
Compatible with various types of casement systems, including:
Thermal-break aluminum alloy casement windows
Inward-opening and inward-tilting windows
Balcony casement doors
Interior partition casement doors
Suitable for whole-home window and door installations in residential projects, high-end finishing projects for real estate developments, and bulk procurement of hardware for the international window and door trade.
