Separately packed roll-up grilles, for instance when using installation covers to protect the trenches from dirt, are rolled up in
the factory. The grille can become slightly over-long due to the steel springs extending. Unrolling the grille and laying it flat
for a few hours can return the grille to its original length. Laying the grille into the trench helps it to fit more easily into the
frame.
