Stopper Plugs

Stopper plug is designed for use from the outside of the enclosure to permanently or temporarily close any unused entries.
In general, care should be taken to ensure that a suitable entry thread sealing washer is also selected and installed, where applicable, to ensure that an effective seal is made at the entry, thereby maintaining the integrity of the enclosure or equipment I.P. rating.

The plugs are suitable for blocking the passage between two compartments and provide pressure balance between the inside and the outside. They enable to expand the box in the future: junction boxes, electrical boxes or devices that require tightness against the dust, dirt or water.
