Secure Gravel Bags not only hold the Secure Cover in place but also create an effective seal by focusing weight on the shoulders at the junction of the side wall and silage sheet. This stops air and water getting into the silage and prevents spoilage.
Secure Gravel Bags are available in packs of 20 (supplied with heavy duty cable ties). Each bag will weigh between 15-20 kg when filled with pea gravel. The integral handle makes moving the bags a simple task.
