Super PULLBOX® Plus Security Tether / Counterbalance
Vulcan Spring’s Super PULLBOX® Plus combines longer extension and greater pull with a ratcheting mechanism. While it can be used as a heavy duty security tether, the Super PULLBOX Plus is often used for counterbalancing hanging signs. The Super PULLBOX Plus combination of features provides the support and pull strength needed for hanging signs along with the ratcheting mechanism to make changing signs easy. Signs stay down when pulled, then with a second tug return to their original position. It is available with a maximum ten foot cable and up to six pounds of force.
Custom Super PULLBOX Plus designs can be quickly and cost-effectively manufactured to create the ideal security tether or counterbalance solution. There are many standard options for the cable, end fitting and box.
