Sizing Guidelines

We can provide custom-made security covers or you can choose from our stock sizes shown below.
For custom-made blankets, please provide the following information: backflow device size, model number and OS&Y's.
Under normal installations, a 20-in. x18-in. cover will fill most 3/4-in. backflow prevention devices; a 24-in. x 24-in. cover fits most 1-in. and 1-1/4-in. devices and a 36-in. x 24-in. fits most 1-1/2-in. and 2-in. devices.
For backflow devices larger than 2-in., contact us for measuring instructions.
