OEM KAVASS Yellow Telescopic Security Bollard – Key-Controlled Height Adjustment, High Visibility Design Suppliers, Factories

When visibility and control matter, this telescopic bollard stands out with its bold yellow finish and secure key-operated mechanism. Designed for parking enforcement, temporary barriers, or access control zones, it rises to full height at the turn of a key—then lowers flush with the ground when not in use.

  • Instant height control – A single key raises or lowers the post manually; no electricity, no complex systems—just reliable mechanical action.
  • Built for outdoor durability – Made from Q235 carbon steel with galvanized base and powder-coated shaft, it resists rust, UV fading, and daily wear.
  • High-contrast warning zone – The bright yellow body features a reflective silver band (30mm wide) for maximum visibility in low light or rain.
  • Secure from the start – The bottom cap includes an integrated lock plate, keeping the internal mechanism protected from tampering.
  • Space-efficient operation – With a 114mm diameter, it offers strong impact resistance without blocking pedestrian paths.
  • Customizable for your site – Available in different heights and colors via OEM/ODM services—add your logo or adjust reflector placement.
  • Factory-direct delivery – As the original manufacturer, we ensure quality inspection and ship within 30 days.
