No spring Quickmount aka rigid. These are designed for overhead pilot car applications, where the chance of the flag being stuck is very low. For any application where the flag might be struck, such as on the corner of a truck or trailer, please use the regular Quickmount with the spring.
Comes with Rigid Quickmount Warning Flag Assembly, Mounting Bracket, Stud, and Hardware. Everything you need, packaged in one unit. This is the premiere flag on the market and is extremely versatile.
