The Restrictor

Description
The new generation of rope lock has arrived. The Restrictor rope lock prevents release of the rope when an out-of-balance condition exists. If the operator cannot overcome the imbalance by physical strength the rope lock will not disengage. The unique handle and cam design enables the Restrictor rope lock to remain closed without the use of an oval ring in an out-of-balance situation. With all steel construction and 41/2" long shoes that grip the rope, the Restrictor is the strongest rope lock on the market.

With the ability to mount on any standard locking rail as well as Tiffin Scenic Studios, Inc. heavy duty locking rail, the Restrictor rope lock is great for new and existing installations. For more information on the Restrictor rope lock, contact Tiffin Scenic Studios, Inc. or an authorized dealer.
