In this paper, the pointfree version of grills is introduced. We consider a Boolean algebra B and a subframe L instead of a topological space (X, τ), and present the concept of approximation θ over B. Moreover, some properties of them are given. Also, we introduce and study the new concepts grill and θ-grill on Boolean algebras.
