About Invisible Connections

Invisible Connections supply the concrete construction industry with ‘unseen’ telescopic connection systems for stairs, landings, beams and columns. We are also specialist manufacturers of the FERBOX® reinforcement continuity system, to application requirements. TSS and RVK Precast Concrete Stair Landing Connectors Elegant and efficient alternative to traditional rolled steel angles (RSA) or corbels to support precast concrete stair landings off core walls. The TSS range is ideal where no screed is intended, enabling a blemish free precast finish to be achieved. The RVK range is deployed with a hopper and is a rugged, cost effective connector for screeded landings. With appropriate layout, robustness requirements are satisfied. DTS Medium Load Beam and Column Connectors Versatile mid load solution for connecting Double Tee floors, slabs and beams as well as miscellaneous applications which fall between performance parameters of TSS / RVK stair landing connectors and BSF beam and column connectors. BSF High Load Beam and Column Connectors Heavy duty and aesthetically pleasing alternative to traditional precast corbel supports, which are complex to detail, expensive to form and challenging to transport. Used for connecting beams to beams, or beams to columns, the BSF range accommodates vertical sheer capacities from 225kN to 1100kN. REDiBOX Permanent Recess Former Purpose designed, simple means of creating recesses in precast or in situ walls to receive cast in TSS, RVK or DTS telescopic connectors. Eliminates digging-out and provides generous tolerance for installation of stair landings. Architects, engineers and contractors who specify Invisible Connections appreciate the reassurance which results from best practice, best products, and best cost efficiency. When constructing concrete cores, choosing Invisible Connections leads to uninterrupted forms, engineering compliance and buildability ease.
