This sandbag extension extends the triangle sandbags with Velcro for tunnels with a diameter of 60cm.
This extension is intended to have 2 triangular fixing bags on top of each other at the tunnel entrance and exit.
The extension is for the triangle fixing bag on top. This ensures that the triangular fixing bag on top stands firmly on the ground and prevents the tunnel from slipping. The extension does not “squeeze” the tunnel and the diameter is retained.

The sandbag extension is equipped with a high quality Velcro.
The colour of the material can be selected from 11 colours + transparent.
