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.
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.
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.
