Built on performance and installer trust, GEWISS is recognised for reliable, high-quality products that are engineered for efficiency, consistency, and real-world installation demands. In this special Who’s Who feature, the company explains why its junction boxes are the perfect choice for electrical contractors.
Leadership in the UK electrical sector is not built on claims, but on site performance, installer trust, and consistency over thousands of real installations. When reliability is non‑negotiable and efficiency is essential, installers across the UK turn to one name above all others: GEWISS.
The box that built the category, reborn for today
With a heritage rooted in engineering excellence and innovation driven by installers, GEWISS has become the benchmark for junction boxes in the UK.
At the core of this leadership is the APTA 44 CE junction box range, a product family that does not simply meet market expectations – it raises them.
Designed to perform across domestic, commercial, and industrial applications, APTA is the clearest example of why GEWISS stands as one of the finest options for junction boxes in the UK today.
Market leaders don’t guess – they listen
APTA was developed from direct installer feedback, addressing the real pressures faced on UK sites, like time constraints, demanding environments, and the need for products that work first time, every time. Derived from the Latin ‘Aptus’, meaning suitable and adaptable, APTA embodies GEWISS’ installer‑first philosophy.
Every feature exists for a reason. Soft‑touch membrane entries enable fast, accurate cable insertion while maintaining full ingress protection. Pre‑threaded M20 side entries allow immediate cable gland installation without drilling. IP‑safe rear entries provide added flexibility without compromising standards. The result is a junction box that reduces installation time, eliminates modification, and delivers confidence from box to box.
One range, every environment, zero compromise
The 44 CE APTA range delivers IP66/IP67 protection as standard, making it suitable for indoor and outdoor installations across domestic, commercial, and industrial settings. From residential gardens and retail spaces to factories and infrastructure projects, installers can standardise on one trusted solution.
UV‑resistant materials ensure long-term outdoor durability in the UK climate, while halogen‑free construction supports safer installations in sensitive environments. Crucially, GEWISS backs up these specifications with substance; every APTA box is individually inspected through advanced quality control processes, ensuring seals, membranes, and performance meet exacting standards.
This commitment to verified quality is a defining reason why GEWISS continues to lead where others follow.
Installer efficiency isn’t a feature. It’s a philosophy.
Available in small, medium, and large sizes, the APTA range offers total flexibility without sacrificing familiarity. Installers benefit from consistent features across all formats, enabling faster work and confident specification.
The flat lid design maximises internal space, simplifying wiring, accessory mounting, and labelling. Quarter‑turn captive screws eliminate stripped threads and lost fixings. Captive lids improve safety during overhead installations. Security seal slots add reassurance in public or controlled spaces. These are not marketing extras; they’re productivity tools refined for everyday use.
Six fixing methods
No two installations are the same, and GEWISS understands this better than most. APTA delivers up to six fixing methods, including internal screw fixing, external bracket mounting, knock‑in and rod fixing, nail gun installation, panel mounting, and cable tie fixing to trays.
This level of flexibility allows installers to adapt instantly on site without compromising IP protection or structural integrity. Patented alignment ribs ensure clean, precise fixing every time, providing proof that speed and precision can, and should, go hand in hand.
True leadership built on systems
GEWISS reinforces its market leadership with purpose‑designed accessories that enhance the entire installation. Supports for the Wago 221 series terminals integrate seamlessly into APTA boxes, improving organisation and accessibility.
The innovative earthing clamp for SWA cable glands redefines best practice, delivering secure, space‑saving earthing while accommodating thermal movement.
This system‑based approach is a clear differentiator, and a key reason GEWISS remains the first choice for professionals who demand more.
Over 40 years of expertise
Since the early 1980s, GEWISS has invested in advanced plastics technology, precision moulding, and electrotechnical design. Supported by an in‑house certified laboratory and total quality control, this depth of expertise allows GEWISS to deliver products that are robust, compliant, and built to last.
