3.3 Metallic and Non-Metallic Doors
Because the RFID field of the GAT NET.Lock 7020 is distorted or blocked by metal (e.g., metallic locker doors), a cut-
out must be made in metallic locker doors into which the GAT NET.Lock Bolt Set 7220 and the label carrier are
installed. A specific cut-out for non-metallic doors is not necessary, only a drill hole for the status LED is required.
Since the reading range of the GAT NET.Lock 7020 is limited, the door of non-metallic lockers must not be too thick.
The maximum door thickness of non-metallic doors depends on the RFID technology and the type of data carriers
used.
3.4 Bolt Gauge
The bolt gauge (GAT NET.Lock Tool 7020, Part No. 1101800) can be used to assist installation in non-metallic
doors. The gauge allows you to easily mark the positions of the drill holes onto the door.
Figure 3.3 – Bolt gauge (dimensions in mm)
The instructions for using the bolt gauge are included with the installation instructions for non-metallic doors (see
"3.10.1 Installation Instructions for the GAT NET.Lock 7020 and Non-Metallic Doors").
3.5 Replacement After Break-In
If the locker has been broken into (forced opening) or if a break-in has been attempted, the entire GAT NET.Lock
7020 must be replaced with a new one. The bolt set and the door shackle must also be replaced.
