Purpose and key benefit: Insulated cover for water meters and exposed outdoor valves that provides frost protection to help prevent frozen meters and pipes, maintaining plumbing system integrity and reducing the risk of winter damage and repairs. Compatibility and size: Fits most water meters and similar devices with dimensions of 54*20cm. Designed to cover meters, taps, and exposed meter boxes of the same size. Material and durability: Constructed from doublelayer waterproof polyester taffeta fabric for longlasting wear. The doublelayer construction delivers reliable heat insulation and durability in repeated seasonal use. Weather protection: Surface treated with a moistureresistant coating to repel rain, snow, and humidity. Keeps the insulation layer dry so the cover remains effective in wet, snowy, or damp conditions. Thermal performance: Advanced thermal design reduces heat loss and lowers the chance of freezing, helping preserve water flow stability and reduce service interruptions in cold climates. Practical advantages: Protects outdoor taps and meters through the cold months, reduces maintenance needs and emergency repairs, and helps prolong the life of exposed plumbing components. Easy to identify fit: Use when the meter or valve measures approximately 54*20cm. Not intended for devices of significantly different size. Use scenarios: 1) Residential winter protection — place over an outdoor household water meter or exposed shutoff valve before freezing temperatures arrive to prevent frozen meters and maintain reliable water access. 2) Seasonal properties and cabins — cover external water inlets or meters at vacation homes and cabins during cold months when plumbing is exposed to low temperatures. 3) Outdoor equipment and work sites — protect exposed meter housings or temporary piping of compatible size on construction sites or landscaping projects when freezing conditions are expected.
