ROHN 3/4X12PP Pier Pin 3/4" x 12" inch for 25G 45G 55G Concrete Base Plate
Made in the USA!
The BPC25G BPC45G BPC55G relies on a 3/4 inch DIA x 12 inch long Galvanized Steel pier pin to align the Base Plate to the slab (Base Plate is a Separate Item) and thus allows the ROHN 25G 45G 55G Guyed Towers to be Mounted onto a Concrete Pier. No Concrete Base Plate can be used as a Self Supporting Base Plate (see 25GSSB 45GSSB 55GSSB). This Pier Pin is also used with 25TG 45TG 55TG Tapered Base Sections.
The Pier Pin as utilized with this Concrete Base Plate is not really a structural load member, but simply a means of fixating the position of the base Plate as to prevent lateral movement during and after Tower Installation. Consult an Engineer for various substitution options. Hole appearing in corner of plate can be utilized for Ground Rod Location or another Pier Pin for more alignment exactitude.
