Abstract: A new Sign Support System for offering a device that is effective and efficient in the hanging of a sign and causes the action to become safer. The inventive device includes a hanger clamp assembly, a stabilizer bar assembly, and a telescopic applicator assembly and "J" hooks. In use, a sign 2 is affixed to the hanger clamp assembly 20 at an upper end of the sign. The stabilizer bar assembly 30 is fastened to the bottom of the sign 2 and serves as a weight which holds the sign taught and causes the sign 2 to resist movement ordinarily caused by air draft or slight wind. The sign support system 10 is then lifted up by use of the telescopic applicator assembly 40 and hooked on "J" hooks or wire, or the like.
