Special Features

  • 【Counteracts Gravity to Hold Door Open】By providing reverse spring force, it effectively counteracts the door's tendency to close automatically due to floor slope or gravity, helping you keep the door in the desired open position.
  • 【Fits Two Common Hinge Sizes】Designed for standard removable-pin hinges with a 5/8-inch radius, and also compatible with 1/2-inch radius hinges. Suitable for bathrooms, closets, and other spaces that require ventilation or safety from pinching.
  • 【Solves Common Door Drift Problem】Effectively addresses the issue of doors (weighing no more than 25kg) that slide shut or won't stay open, offering a simple repair solution for a common door malfunction.
  • 【Flexible Installation with Complete Kit】The set includes 4 spring tools, providing ample parts for self-opening doors. For hollow composite doors, installation on the top hinge is recommended. For standard solid wood doors, installing one on both the top and middle hinges is advised for optimal performance.
  • 【Application & Installation Notes】Suitable for most interior doors (e.g., solid wood, composite doors). Not intended for heavy metal doors. Before installation, ensure the hinge pin is removable, and follow the recommended quantity based on door weight and type.

Description

Product OverviewEasily solve the common problem of doors that won't stay open with this 4-PCS door hinge spring repair kit. Designed to provide reverse-acting tension, these Z-shaped springs help counteract gravity and floor slope, automatically resetting hollow core, composite, and standard solid wood doors to a stable open position—perfect for improving ventilation and accessibility in bathrooms, closets, and interior rooms.
Package Quantity: 4 hinge springs (complete repair kit)
Material: Durable spring steel
Color/Finish: Metallic silver (natural steel)
Compatibility: Fits standard removable-pin butt hinges with 1/2" and 5/8" radius
Design: Z-shaped, reverse-acting coil spring
Door Weight Limit: Recommended for doors weighing up to 25 kg (approx. 55 lbs)
Use: Door repair, automatic door reset, preventing door drift
Complete 4-Piece Repair & Upgrade Kit: Includes four identical Z-shaped hinge springs—enough to install on multiple doors or use the recommended configuration (top and middle hinges) for a standard solid wood door, ensuring balanced tension and reliable performance.
Dual-Size Compatibility for Common Hinges: Engineered to fit standard removable-pin butt hinges with both 1/2-inch and 5/8-inch radii. This wide compatibility covers most interior door hinges found in homes, apartments, and offices, simplifying your search for the right solution.
Reverse-Acting Tension to Hold Doors Open: Once installed, the spring creates a gentle reverse force that counteracts the door's weight and any floor slope, preventing automatic closing. This allows doors to remain safely open for ventilation, moving items, or accessibility.

Versatile for Interior Door Types: Effective for hollow core doors, composite doors, and standard solid wood interior doors.
