ROHN's R-BPL25G top-mounted bearing plate is engineered specifically for use with the Rohn model 25G tower sections. It is designed with extra long tubular legs to provide maximum clearance for the installation of equipment and it bolts directly to the top of a standard 25G tower section with the included section bolts. It has integrated guy lugs and has been pre-drilled to accept the ROHN R-TB3 and R-TB4 thrust bearings so you can use it with a variety of tubular mast pipes and rotors.
