Helnor lock cup is included in all Helnor street boxes.
The locking cup sealing cap is included in the option.
When using the Helnor locking cup, the gate box is easily sealed so that operation of the spindle extension is not possible without breaking the seal.
The locking cup is easily put in place, down in the street box, above the spindle extension. Disassembly of the street box is not possible without breaking the seal.
The seal is broken by punching/cutting holes in the lid of the locking cup, and then tilting it up.
The locking cup fits in all Helnor street boxes.
