Please note: This item is a single fixing screw for Ingersoll SC71 or SC73 Automatic Rim Deadlocks. Please specify whether you require brass or chrome finish. Orders recieved without a finish specified will be dispatched at random. If you require a pair of screws you must order 2 of this item.
The NS80 automatic Rim Deadlock has been out of production for many years, and replacement locks are no longer available. If your main spring breaks (a common cause of failure on the NS80) this replacement spring (custom manufactured to original specs) can give your lock a new lease of life.
Please note: Replacing this spring will require disassembly of your lock. Some technical ability and basic DIY tools may be required, and eye protection should be worn at all times when handling springs. No instructions are provided with this item, and no technical support can be offered.
