CB1 - Carriage Bolt Adapters

5/16x1.2" OD, 100 ea. -

These Carriage Bolt Adapters raise the neck of a carriage bolt so it doesn’t touch the sign face, thus extending sign life. Made of black Nylon, they have sloped sides to prevent the head of the bolt from being grasped and turned. 

Raising the carriage bolt neck protects the sign face from the damage caused when a square-neck carriage bolt is forced through the round hole in a sign. This breaks the bond between the sign face and it's substrate, allowing weather to deface the sign.

Carriage bolt adapters are available in black only - bolts purchased separately.
