BAND-IT ULTRA-LOK Cable Clamps Reduce Cable Theft | Case Study
April 8th, 2021
Cable Clamps
Cable Theft is a Growing Problem Worldwide
Cable theft occurs globally, but in South Africa it’s fast becoming a national crisis.
Estimates put the loss between 5-7 billion Rand (423 – 593 million USD) a year, with serious implications for the country’s economy, reliability of electricity supply and security.
Cable thefts can cause power outages that could last for days, with copper cable thefts constituting more than 90% of all these thefts. The cost of replacing the metal has a significant disruptive effect on industry and contributes to increased tariffs and prices for ordinary South Africans. Furthermore, the replacement of stolen LV MV HV cables has to take preference over essential maintenance.
Tamper Resistant ULTRA-LOK Cable Clamps
To deter theft, the security of any traditional cable installation can be increased by applying an ULTRA-LOK clamp as frequently as every 150mm of cable. The effectiveness of the ULTRA-LOK cable clamps was recently proved at a client site in August 2015. The client operates in the petrochemical industry, where conveyer belts are located in secluded areas and are difficult to monitor making cable theft monitoring a major challenge. The verdict, after looking at various BAND-IT ties, was that the ULTRA-LOK open end clamp and installation tool would be the best suited to the client’s projects.
BAND-IT’s team was tasked with supplying the client with application tools and clamps, and provided training to the operators that installed the clamps.
INSTALLATION: UL4000-D TOOL
For installing the BAND-IT ULTRA-LOK clamps out in the field, the BAND-IT UL400-D tool is recommended, as it is ideal for mobile installations. The UL400-D power tool uses pre-set tension settings with ULTRA-LOK bands to consistently achieve maximum clamping strength. One tool tightens the clamp and cuts off the tail right at the buckle for a smooth installation. Powered with a Lithium-ion battery, the UL4000-D battery charge lasts longer with consistent peak performance through the life of the battery.
- Speed: Installs cable clamps 3-5x faster than hand tools
- Strength: 20% stronger than BAND-IT band & buckle, full tension lock, provides tighter clamp than band & buckle
- Easy to use: Training takes minutes, reduces mistakes vs. stainless steel band & buckle
- Save money: Faster installation provides lowest installed costs, power tool eliminates costly training vs. band & buckle installation tools, increases productivity and quickly move to your next job
- Safety: Less time spent in hazardous work zone, reduces injuries caused by hand tools, reduces fatigue and chronic ailments caused by hand tools, optional UL Safety Belt available

Stainless Steel Cable Ties Replace Plastic Ties In Harsh Environments
April 8th, 2021
Stainless Steel Cable Ties
BAND-IT Cable Ties
Shine At Precious Metals Refining, Smelting Complex
The conditions in the refinery complex are unique due to its highly-corrosive and hazardous area atmosphere, as even 304 stainless steel is subject to rust after an extended period. Therefore, the specific requirement was for high-strength, durable cable banding / strapping solutions to cater for these challenging conditions. Previously the company was using plastic cable ties for the facility’s electric cables, which proved not durable in the harsh operating environment.
Over a five-month period, Banding & ID Solutions Africa has been upgrading the tying system used on the cables at the refinery complex using a mixture of reusable BAND-IT cable ties. To date, it has supplied about 10,000 reusable BAND-IT cable ties to the company.
BAND-IT Cable Ties Outlast Plastic Cable Ties
The cable straps are expected to last up to five years before they need to be replaced, which is significantly longer than the six-month lifespan of the plastic cable ties (non-metallic) used previously.
In addition to BAND-IT Ties being well-suited to the application at hand, the contractor was impressed that the cable ties were easy to install using a ratchet-operated BAND-IT C075 Bantam strapping tool.
BAND-IT Ties
Thorne & Derrick distribute Stainless Steel Cable Ties manufactured by BAND-IT for bundling, strapping and locating low, medium and high voltage MV HV cables.
Cable ties manufactured from stainless steel are used in industrial and hazardous area locations where high temperature and exposure to corrosive atmospheres requires a high security cable tie and clamping solution – the cable ties provide excellent resistance to weather conditions, UV radiation, extreme temperature, aggressive chemicals or fire.
The cable ties are used to bundle, fasten, clamp and tie LV MV HV cables onto cable containment including cable tray, ladder or basket. The high strength, corrosion-resistant cable ties provide excellent support for all types of power, control and instrumentation cables with resistance to chemical corrosion, UV and vibration.
We provide competitive prices for stainless steel cable ties and cable cleats and cable hanging systems from extensive stocks to UK and international destinations.
âž¡ Thorne & Derrick stock and distribute the complete range of Band & Buckle products and tools manufactured by BAND-ITÂ from stainless steel used to fasten, strap and clamp LV MV HV cables, pipes and hoses.
