Due to space constraints, our vestibules were not able to be a full 10' wide between our doors, thus the recessed walkoff mats aren't 10'. Does anyone see any issue with supplimenting the distance with a roll-off mat (properly maintained of course) laid out at the other side of the vestibule? The end result would be more than 10', but it would have a couple inch "break" as you passed through the door from the vestibule into the lobby.
