The Yard Guard 8' Double Chamber Water Bag (WB8D / WB8D5) is a durable, weather-resistant solution designed to secure in-ground and above-ground winter pool covers throughout the harsh winter season. Built from heavy-gauge, UV-treated vinyl, these water bags help prevent your winter cover from shifting, lifting, or collapsing under the weight of snow, ice, and strong winds.

Engineered with a double-chamber design, these bags provide added stability and redundancy—ensuring your cover stays firmly in place even if one chamber is compromised. The large fill valve accepts a standard garden hose, making setup fast, easy, and mess-free. Trusted for years across North America, Yard Guard water bags deliver reliable winter protection for your pool investment.
