This is a set of protector rails for the Yaesu FT-891, 857D, and select other models 

1 order is for 4 pieces which join together to make 2 larger pieces, 1 for each side.

This is a complete kit you just and you can use the same screws provided with the radio (bracket for mobile installation), if you don\'t have these screws, 4x M4x10\'s would work

* This is for the rails only, Radio not included
