South African manufacturer Pratley continues to demonstrate its engineering leadership with its adjustable cable gland, designed for use across a range of industrial applications and to reduce maintenance and labour costs.
“Our adjustable cable gland offers exceptional cost savings, versatility, durability and efficiency,” says Tristan Blades, Technical Projects Manager. Its adjustability allows it to accommodate everything from paper-thin braid armouring to thick steel wire armour. The interchangeable nipple design also allows for extended-length nipples, making it ideal for applications involving thicker gland plates, which is where conventional glands usually fall short.
A key cost-saving feature in the gland’s design is the built-in spigot. This allows a smaller gland to fit securely into a larger knockout hole, such as an M20 gland into an M25 knockout, minimising the need for different gland types and streamlining inventory requirements. “It is a solution that makes installations quicker and more flexible,” Blades notes.
Furthermore, Pratley’s 95% stock availability policy and commitment to customer service mean that replacement parts are readily available. This supports minimal operational downtime and quicker turnaround times for repairs.
“A manufacturer offering near-total stock availability on the shelf can make an enormous difference,” says Blades. “It eliminates delays related to manufacturing lead times and helps maintenance teams keep operations running smoothly.”
Durability is another standout feature. Unlike ordinary cable glands, the adjustable cable gland’s loose cone bush is made from a special high-tensile brass to prevent distortion under tightening or mechanical stress. In addition, the loose cone bush allows it to self-centre under the armouring automatically, ensuring the best grip on each armour wire.
The gland also incorporates a differential nut which features two slightly different coarse pitch threads. This achieves the mechanical advantage of an ultra-fine pitched thread, strengthening the gland’s clamping ability. “It is like having the clamping advantage of a virtual thread, or like having a built-in gearbox in the gland,” Blades adds.
Feedback from the field highlights the positive impact of the innovative adjustable cable gland. “Many of our customers have reported significantly lower maintenance costs using this cable gland. And it is such an easy gland to install. Additionally, as one gland that can be used across multiple armoured cable applications, it simplifies the installation process and delivers long-term savings,” Blades highlights.
Pratley has a policy of producing products that out-perform all comparative products on the world market. “It is something we live and breathe by, and our adjustable cable gland meets that mark,” says Blades.
