Welcome

We specialise in the Engineering, Design and Manufacturing of niche products and solutions against Vandalism and Theft. Our enclosures are used to house telemetry, radio, batteries and monitoring equipment in remote areas. Our stainless steel transformer doors are used in substations and pump stations where copper theft is a major problem. Our manhole covers are used when security may not be compromised. Our solar panel protection frames can handle the rigorous attacks seen in remote areas.

Locks, Hinges and Related

Locks picture

Most commercial locks are easily damaged by inserting foreign objects into the lock barrel. We hold several patents on specialised locks to prevent damage de to vandalism. Some of our systems include:

  • - Magnetic Lock Cover system
  • - Hydro Lock - resistant to mud, silt and water
  • - i.Lock - Electronic lock with full audit trail. IP67.
  • - Electromagnetic servo lock - no keyholes 

We also build a range of related heavy duty Ironmongery: Hinges, tower bolts, barrel bolts, hasp and staples, etc.

 

 

Custom Developments
