3.10.1 Installation Instructions for the GAT NET.Lock 7020 and Non-Metallic Doors
Complete the following steps to install the GAT NET.Lock 7020 into lockers with non-metallic doors.
► Drill 3 holes (3 in Figure 3.9) for the GAT NET.Lock 7020 into the locker wall inner side.
NOTE! Position the 3 holes according to the measurements in Figure 3.9.
► Plug the connection cable into the GAT NET.Lock 7020 (see "4. ELECTRICAL CONNECTIONS") and loop the
cable in the bottom of the lock.
► Mount the GAT NET.Lock 7020 with 3 screws (3) onto the locker wall inner side.
NOTE! Use the correct screws according to the type of locker material, max. Ø 4 mm (0.16 in). The
maximum allowed tightening torque of the screws is 2 Nm (1.47 lb-ft).
► Mark the mounting holes (4 in Figure 3.9) for the GAT NET.Lock BoltSet 7120 and the hole for the LED (5) onto
the locker door inner side. This can be done using the installation diagrams on the previous pages or using the
bolt gauge (see “3.4 Bolt Gauge”).
► When using the bolt gauge for marking:
► Insert the bolt gauge onto the front of the installed GAT NET.Lock 7020. The bolt gauge can only be
inserted in one orientation and snaps onto the lock.
► Close the door so that the center points on the bolt gauge mark the hole positions onto the locker door
inner side.
NOTE! For doors made of softer material, moderate pressure is sufficient. For doors made of harder
material, press the door with sufficient force so that the drill markings are visible.
► Remove the bolt gauge from the GAT NET.Lock 7020.
► Drill the three marked mounting holes (4) to the required depth and diameter according to the screws used.
► Drill the hole for the LED (5) through the locker door. The recommended drill hole diameter is 10 mm (0.4 in) or
8 mm (0.3 in) when using an LED cap (see following instructions).
► Attach the bolt set to the locker door inner side using 3 screws.
NOTE! Use the correct screws according to the type of locker material, max. Ø 4 mm (0.16 in). The
maximum allowed tightening torque of the screws is 2 Nm (1.47 lb-ft).
► To cover the LED hole, a label (GANTNER design or customer-specific design) can be attached to the front of
the locker door. A transparent (matt) window for the LED must be incorporated into the label.
NOTE! For customer-specific labels, ensure that a transparent window for the LED is incorporated in the
design and that no metallic films or colors are used.
Alternatively, the LED hole can be covered using a transparent LED cap (GAT LED Plug 8mm, Part No.
806325). In this case, the LED hole must be 8 mm in diameter.
► Test the installation to confirm the following requirements:
o That the locker door closes easily.
o That the door shackle inserts correctly into the GAT NET.Lock 7020. The locker door must spring
open without assistance after it is unlocked.
o When the door is pressed shut, ensure there is no gap between the bolt set (2) and the front of the
GAT NET.Lock 7020. Ideally the bolt set should touch the front of the lock (see measurement in
Figure 3.9).
