100% Recyclable, green marker post The Rhino VentGuard™
Utility Marker

The Rhino VentGuard provides a high-visibility marker that never needs painting. Special vents allow for air flow, and the cap protects against precipitation.

Using a VentGuard increases the visibility of the vent pipe, making it less likely to be hit by off-road vehicles and equipment.

The VentGuard is available in three styles/sizes:

  • 2 inch Iron Pipe Size (IPS)
  • 3 inch IPS
  • 4 inch IPS

VentGuard Options

  • Reflective bands

The VentGuard features easy installation:

1. Cut off the top of existing vent pipe.

2. Slip the factory assembled VentGuard over the vent pipe.

3. Install set screw through the VentGuard into the vent pipe.
