Why do the installation instructions call for such an oversized recessed block out for frame installation?
A. There are many variables in deciding how to install frame. The field condition and finish floor type are the two most important factors. The standard instruction covers the typical installation where there is an oversized recess to set the frames and then is backfilled with grout. Typically there is a tile, carpet or terrazzo floor that will then be installed to about the installed Pedigrid frame. In the case where there will be exposed concrete adjacent to the installed frame, the choice would be to create a block out of the recess, Option #2 of the frame offerings would then be recommended followed with caulk or grout in the small gap left between the frame and the finished floor.
