3G135
Description: HIGH SECURITY "CASTLE" RANGE DEADLOCK
Purpose
The 3G135 has been developed to satisfy a market requirement for a version of the 3G110 Castle Range lock which has greater key security than the standard lock.
Overview
Normal environment conditions, envisaged abuse conditions, design and perfoemance standards, operating life and reliability.
These factors are as for 3G110 (HLPS 1066) except for the advantages which are given by the special features listed below.
Features
Castle Range detainers are used. Ten lifts are provided, one lift being higher than can be cut from any existing Chubb key blank giving 74,000 usable differs. (The positions of the remaining nine steps do not correspond with those of the standard Castle Range).
The key has a specially shaped bit section which makes impossible the task of cutting a key blank from a simple flat sheet. Key blanks will not be supplied to customers.
In Master Keyed suites, differs are restricted such that each Master Combination has at least two steps at the highest lift position.
The key blank is a Registered Design.
Range
The lock is available in satin finish only (3 keys/lock).
For the future, the key bit section may be varied to increase the number of differs available.
