FERBOX provides the continuity between wall and floor reinforcement. This continuity strip solution is manufactured to precise application requirements and is in daily use by the industry’s leading concrete frame contractors.
Invisible Connections’ manufacturing scope is unrivalled in this product sector, so engineers and contractors benefit from bespoke fabrication to site specific dimensions without the need for any on site modification. FERBOX customers can therefore have confidence that design intent and quality assurance will be met as well as timely delivery and ease of installation.
For design intent and construction practicalities to be achieved, as well as the quality assurance needs of professional stakeholders to be met, the UK concrete reinforcement sector adopts this process as standard:
This rationale also applies to threaded couplers.
Yet when it comes to reinforcement continuity strip, such checks are often inexplicably dismissed. What is more, since reinforcement continuity strip is subject to the additional demands of rebending on site, it should result in higher levels of scrutiny, not less.

Continuity strip is sometimes regarded as an insignificant ‘accessory’ and brought into the UK without any recognisable form of approval. Such products tend to be entirely ‘standard’ in their configuration, with a ‘one size fits all’ approach to anchorage, lap and casing length. Frequently proving to be wasteful in application, these products offer little to address the needs of reinforcement design.
However, CARES approved continuity strip manufacturers are adept at the timely fabrication of their products, accommodating principal design and construction practicalities.
Varying reinforcement and casing dimensions to suit, results in what we know as ‘specials’. For UK CARES approved fabricators, these variations are simply incorporated and help to ensure that design intent is met, whilst also making life much easier for contractors.
Reinforcement continuity strips are important structural components which require performance validation. CARES Technical Approval provides this validation through a process of structural testing, regular mechanical testing and audit. This meets the quality assurance needs of professional stakeholders and enables compliance with the National Structural Concrete Specification (NSCS) published by Construct Concrete Structures Group.
For good reasons over 90% of FERBOX reinforcement continuity strip is made-to-measure, which has many efficiency advantages for concrete frame construction. Here’s our top 10:
