Tyco Fire & Building Products offers the DSB-1 dry sprinkler boot for freezers.

Tyco Fire & Building Products, a business unit of Tyco Engineered Products & Services, offers the DSB-1 dry sprinkler boot for freezers. The DSB-1 combats the potentially damaging temperature changes that can adversely affect dry sprinklers installed in freezers. The DSB-1 dry sprinkler boot is an EPDM, 50 durometer-type rubber boot designed for installation with all vertical or pendent dry sprinklers. Once installed, the boot creates an airtight seal, eliminating the build-up of potentially dangerous condensation by maintaining consistent temperatures both outside and within the freezer area.Tyco Fire & Building Products.
