Sometimes there just isn’t enough room in a base cabinet, or some other confined workspace, to get the leverage required to install compression-fitting angle stops. In this situation, I turn the angle stop instead of the nut that secures it to the supply line. As shown in the drawing, I enclose the angle stop’s nut with a pipe wrench braced against the cabinet floor. The basin wrench grabs the body of the angle stop, which is then threaded into the nut held by the pipe wrench. If I need a little extra torque, I add a crescent wrench to the team.
