Multi-Size Sliding Door Limiting Guide Wheels: The “Precision Control Assembly” for Stable Door Operation – This set of sliding door limiters (anti‑swing devices) is specially designed for framed doors, automatic doors, glass doors, and other types of sliding doors. It includes three different specifications to accommodate a variety of door widths:

• Fixed Version with a 38mm Fixed Hole Spacing: Ideal for doors with a width of less than 13 mm, this version provides stable control over door movement after installation, effectively preventing lateral drift and misalignment.
• Standard Adjustable Version with a 21mm Fixed Hole Spacing: Designed for doors ranging from 12 to 45 mm in width, this adjustable model offers optimal stability and compatibility by adapting to most standard sliding doors through simple structural adjustments.
• Widened Adjustable Version with a 38mm Fixed Hole Spacing: Suitable for doors measuring 15–45 mm in width, the widened design delivers enhanced stability while allowing users to replace existing fixed‑plate anti‑swing devices without the need to re‑drill mounting holes.

These components integrate both guiding and limiting functions: they not only ensure smooth, controlled sliding motion but also prevent swaying and misalignment during operation. With their easy installation and reliable performance, they are essential accessories for enhancing the smoothness and stability of sliding door systems.
