Two universal clamps are required to mount one of our post mountable signs to a pole (one for each rail). The universal clamp provides adjustable sizing, allowing easy mounting to any pole from 45mm to 217mm including odd pole profiles. This clip is useable with any sign from our post mountable sign range.
To mount two signs to the top of a post, a set of back-to-back clips are required to hold the rails. This, unfortunately, will not work with the universal sign clamps as back-to-back clips are a set length to fit with the Rigid-D clips. Therefore, we recommend using a 76mm pole in situations where signs are required facing both ways. It is possible to mount two signs back to back with the universal clips, however, the signs will not be level with each other.
