VK681 - Model V-BB (Back to Back) Specific Application Attic Sprinkler

The Viking Model V-BB (Back to Back) Attic Sprinklers are UL Listed for both wet and dry pipe systems in combustible and non-combustible sloped attic spaces, and can be installed with steel or CPVC piping. (CPVC is allowed on wet pipe systems only.) When used with Viking's Model V-SD (Single Directional) and VK696 Attic Upright sprinklers, it is possible to utilize a single line of piping at the attic peak, eliminating the need for branch lines and greatly reducing the number of required sprinklers and associated materials. The Model V-BB is a glass bulb design with a temperature rating of 200° F, and is offered in either standard brass or ENT plating for areas subject to corrosion. The Viking Model V-BB Attic Sprinkler provides a reduced response time due to its narrow ridge spacing of 6 ft (1,8 m) and long throw pattern (up to 30 ft in each direction measured horizontally), and is offered in three different slope ranges and two different orifice sizes (K=5.6 or 8.0).
