Self-Closing Sliding Door Closer, with Hold Open, Adjustable Speed and Tension (0.3–1.0 kgf), Ideal for Lightweight Patio/Screen/Closet Doors, L70 Pro

Engineered for homes & commercial spaces, this Pneumatic Sliding Door Closer combines functionality, durability and user-friendliness—perfect for screen sliding doors, especially in summer. Made of premium aluminum, its ultra-slim 2.2cm mounts above the sliding door frame, blending with decor. Its rust-resistant design withstands North America’s varied climates. Its patented pneumatic core enables slow, silent automatic closing—no slams or damage. When released, the door glides shut quietly, ideal for bedrooms, patios, screen doors and noise-sensitive areas. Closing speed adjustable via end air pressure knob, from quick for high-traffic to slow glides. Hold-open function: extend inner rod to max, push to lock open (great for ventilation). To unlock, pull rod toward closing; it disengages automatically for smooth closure—ideal for screen doors needing summer ventilation. Versatile with 9 sizes (60-100cm) to fit most sliding doors, including screen doors. Critical size notes: installation needs extra 2cm; inner rod extends 4cm shorter than body (reduces max door opening by 4cm). Ensure rod extension is slightly less than door’s max travel; otherwise hold-open fails, and a too-short rod limits opening width. Closing force (0.3-1.0kgf) adjusts via inner rod screw, fitting lightweight closet, screen, and patio doors. Note: If door resistance >1kgf, may not close fully. Test: push with one finger—easy glide means suitable. Installation: included screws/metal plate; no tools needed.
