****When a torsion spring grille, tile bridge, and enclosure are specified, the grille will mount to the tile bridge only and not to the enclosure’s torsion tabs. The enclosure will need to be secured to the tile bridge via four 8-32 screws (not included). [In some cases, the enclosure may need to be rotated to avoid the torsion tabs and insure a proper fit.] See SL3-1431 for additional information.

EQ81 tile bridge works only with 96-8 Series enclosures.
