FrostGuard™ Insulated Blankets
If an unexpected freeze occurs and you have not winterized your backflow you could have costly repairs on your hands. Protect your backflow assembly year round from sudden cold snaps that can occur in early winter or late spring with our FrostGuard™ Insulated blankets. They will blend into your landscape better and offer superior protection to unsightly burlap wrap.

Install the FrostGuard Blanket easily by just slipping it over the assembly; with 9 standard sizes that cover most 1/2" to 8" inline assemblies. They come in 2 choices of industrial grade, resilient, crushable, compressed fiberglass insulation, R-13 or R-30. Our rugged blankets are double stitched and the seams are heat treatred to ensure a solid bond. The heavy 14 oz water repellent vinyl fabric used is UV & mildew resistant and fire retardant to meet NFPA-701 / ASTM E-84. They can be left on year-round for your convenience.

Reinforced grommets on the bottom seams are standard and allow a padlock to be used to lock your FrostGuard in place. Any RP relief valve discharge is unobstructed, even when bottom seams are padlocked together for best insulation protection.

These blankets fit inside of our standard cages & are available in Forest Green or Woodland Tan to compliment your landscaping.

Some cheaper blankets from the competition will quickly begin to decompose in the sun. Our blankets will last season after season.
