The Cordless spring unit device for faux wood Venetian blinds is a sealed, constant-force lift core designed for 50 mm (2″) faux wood and composite blinds. It replaces traditional cord locks with an internal 301 stainless-steel spring and brake hidden inside the headrail, delivering cordless, child-safe lifting, smooth hover at any height, and quiet motion. Suitable for blind sizes up to 2400 × 2500 mm and weights around 1.5–4.5 kg, this modular device lets OEM brands standardize their faux wood programs, simply tuning pre-tension for different fabrics while supporting North American and European cord-safety expectations.
Motor Venetian blind accessories for cordless lift systems combine manual cordless lifting with motorized tilt in a single headrail platform. Designed for faux-wood and aluminum Venetians up to 2.4 m wide and 3.0 m high, the system keeps the lift path fully cordless for child safety while a low-voltage tilt motor controls the slat angle quietly and precisely. OEM fabricators can use this modular accessory kit—springs, motors, brackets, couplers and wiring harnesses—to upgrade existing Venetian ranges into hybrid cordless + motor products without retooling the headrail, improving safety, comfort and ASP in one move.
The DOSRON Cordless Spring Unit Device is a sealed constant-force lift core for child-safe Venetian blinds, roller shades and Roman shades. It replaces cord locks with an in-headrail spring that keeps lift force stable, even on heavier slats. Factory-tuned versions for 2, 5 and 8 kg loads let fabricators standardize shade parts and roller blind components across multiple programs. The same platform links with motor Venetian blind accessories and DC tubular motors to build hybrid spring + motor solutions, reducing SKUs while delivering smooth motion, long cycle life and motor-ready cordless window coverings. Engineered under ISO 9001 with RoHS-compliant materials.
Compatible motorized louver accessories and spring systems form a modular hardware toolkit for plantation shutters, faux-wood venetians and small architectural louvers. Motors, gearboxes, shafts, brackets and stainless-steel spring cartridges share common interfaces, so OEMs can cover multiple product lines with one cordless tilt platform. Spring-assisted balance reduces required motor torque, improves hold-at-position stability and helps keep operating noise below 40 dB. Designed for IP20 indoor environments with 10,000–30,000+ cycle life targets, the system supports battery or low-voltage drive options and future smart-home upgrades, making it a robust base for child-safe, motor-ready window covering projects worldwide.
Honeycomb Shade Components from DOSRON provide a complete hardware platform for modern cellular blinds, covering aluminum headrails, bottom rails, brackets, side channels, handles, and drive options. The system supports both cordless spring and low-voltage motorized lifting for smooth, quiet and child-safe operation in bedrooms, nurseries, RVs and small offices. Optimized for 25 mm and 38 mm honeycomb fabrics, these components protect delicate cells while controlling light, privacy and energy efficiency. OEM/ODM brands can mix and match Honeycomb Shade Components to build differentiated product lines while keeping a standardized, easy-to-assemble hardware base.
Hybrid Manual & Motorized Top Down Bottom Up Drive Unit is a compact in-headrail solution that combines spring-balanced push-pull control with a quiet low-voltage motor. Homeowners can adjust top or bottom rails by hand for quick, cordless operation, then switch to motorized scenes for schedules, remote commands, and smart-home integration. The spring core reduces motor torque, noise, and energy use while preserving power-off usability. Designed for honeycomb and fabric shades, this hybrid platform helps OEM and ODM partners meet child-safety expectations and upgrade existing cordless programs into app-ready, value-added shading systems, ensuring stable performance across widths and fabrics worldwide.
Custom Top Down Bottom Up Cordless Blind Fittings for Child Safety Window Coverings are engineered hardware kits for OEM and ODM blind manufacturers who need a safe, cordless solution. The system replaces external cords with an internal cordless spring mechanism, enabling smooth top-down and bottom-up operation for honeycomb, cellular, and Roman shades. By tuning torque and friction inside the module, the fittings hold the shade at any position while keeping façades clean and cord-free. Compatible with common aluminum and steel headrails, these cordless blind fittings can be customized for different rail profiles, fabric weights, and regional safety requirements. They are ideal for child safety window coverings in nurseries, kids’ rooms, schools, and residential projects where both safety and modern design are critical.
The Cordless Top Down Bottom Up Spring Lift Mechanism is a compact in-headrail core for honeycomb and fabric shades that removes exposed cords and improves child safety. A spiral spring and guided friction balance the shade weight so users can raise the bottom rail, lower the top rail, or hold the panel at any position with light, smooth push-pull force. Designed for OEM programs, this cordless top down bottom up spring lift mechanism supports typical residential widths, documented pre-tension windows, and lab cycle-life testing, giving brands a stable, quiet, and repeatable platform for premium cordless shades worldwide.
The DOSRON Customized Cordless Spring Mechanism for Honeycomb Blind uses a precision-engineered spiral spring system to deliver smooth, balanced, and silent lifting motion—without external cords. Built from durable POM housing and a 301 stainless steel spiral spring, it provides consistent torque and long life. This mechanism offers a safe, maintenance-free, and energy-efficient solution that enhances both functionality and aesthetics in modern window shading systems.
The DOSRON 32mm Cordless Tubular Motor combines precision, silence, and smart control. Designed for modern roller shades, it delivers stable torque, long battery life, and seamless integration with smart home systems—ideal for residential and commercial automation projects.

No. This system is engineered for manual cordless zebra blinds. Hybrid motor-spring platforms use different control logic.
It depends on measured fabric + bottom rail weight and required drop. Use the selection table to choose model and quantity per Shaft.
Pre-winding stores initial energy so the system enters the intended force band immediately. The Pin locks the pre-tension state.
Not reliably. The Spring Box defines the force band; the Brake only governs motion within it. Correct selection comes first.
Yes, but only with proper load calculations to keep force distribution stable across the full travel.
Dosron designs high-performance spring systems and motors for cordless blinds.
