Plastic molded T20 Mounting Block, allowing a Gallagher T20's wires to be connected to field wiring in a tamper proof environment. 

Extends the T20 rear tamper to detect both wall removal of the block and T20, and T20 unit removal from the block. 

Supports field cable entry via conduit connection through the side, top or bottom of the block. 

Ideal for mounting the T20 in locations where rear cable entry is not possible (e.g. historically protected buildings).
