Meet the team

Introducing some of our key people. We’re here to help.

Derek Brown

Operations Director

With over 30 years as a product specialist within the construction industry, Derek’s most notable success was originating the first reinforcement continuity strip product to achieve widespread appeal, ‘Kwikastrip,’ which he built to become the market leader, before being acquired by Halfen in 2001. More recently, after more than a decade in high profile positions within the supply sector, Derek recognised the opportunity to renew his owner-manager experience and teamed up with the Norwegian manufacturer, Invisible Connections AS, to become their UK partner. At the same time, Derek renewed his manufacturing leanings by establishing the current factory in Thame, Oxfordshire, principally to manufacture the FERBOX reinforcement continuity system.

Derek places high value on building long-term relationships with customers, suppliers and colleagues via an honest and earnest style of management.

Lesley Brown

Finance Manager

Lesley has enjoyed a long career in finance, working freelance for several SMEs. She is used to collaborating closely with owner-managers and producing detailed management accounts, which she supports with interpretation and advice. Lesley has worked for architects, developers and together with Derek for many years, so is familiar with the customs and practices of the construction industry. She takes pride in doing as she says and does her best to inspire a similar mindset in her financial counterparts at customers and suppliers!

In recognition of his contribution in establishing Telescopic Connectors as the preferred method for connecting precast elements amongst within the UK concrete construction community, and the expansion of Steve’s role to support iC projects internationally, Steve was promoted to Technical Director in 2025.

Invisible Connections are an outstanding company to work with. Between Ross in sales and Derek on the technical side of things, iC have an offering which the rest of the market would do well to get close to. I can’t credit these two individuals enough for the support they have given me for both standard and bespoke FERBOX connections – some rather more complex than others!

Telescopic connectors provide us numerous advantages for precast stair installation. Apart from improved time and efficiency, the health and safety gains over traditional support methods are a key driver to satisfy our own needs, as well as those of our clients.

We were thinking how we could give the architect what they wanted: a finished landing with a shadow gap all around. We used the telescopic connection system from Invisible Connections, which made it a lot easier, both to install the wall recesses and to install the stairs.

An issue with slipform is dragging. We always try to find solutions for fixing the casting elements robustly. Singular couplers are flimsy (just tied individually to the wall rebar), but coupler boxes are more robust and can resist that drag. COUPLER CADDi is a really good solution for slipform systems.

I’ve used your services on my last three projects (telescopic connectors for precast and continuity strip for in-situ). You’re very good at accommodating site demands for lead-in times and value competitiveness. Very happy with the service I’ve received on all three projects and hope this relationship will continue on future developments.

Having FERBOX pre-sized is great from a quality and time-saving perspective, because if you use a regular continuity box, you end up having short lap lengths, depending on where you cut it. It goes back to your time spent fixing, looking for things, cutting them and having to retape corners and ends to stop concrete going in.

As specialists in precast concrete car park construction, we use telescopic connectors for many key applications. Particularly, the BSF system helps us to construct a ‘modern’ frame without cumbersome corbel supports and enables rapid assembly on site. The technical back-up provided by Invisible Connections provides us with added reassurance.

In a slipform core, having several couplers in a box actually makes it easier and quicker to find. Just take off the lid and the couplers are exposed without any damage.

Thank you for sending the calculations and installation advice. The new calculation software looks great. Very clear, user friendly and with more design checks than the previous version. It’s a pleasure to see how you are constantly improving.

We have completed installation of our stairs in both cores, using TSS connectors. Everything went smoothly, quickly and easily. The new anti-uplift brackets have done the job perfectly.
