2a.
For center-of-tile installations,
align the end bracket with the center-
of-tile slot of the T-bar rail (with the
side facing the opening of the center
gate assembly), as shown to the left.
NOTE: For the UL Listing, when the
48-inch/1220-mm length VB2, VB3, or
VB4 Bracket is used with the VS1 (V35)
Flexible Dry Sprinkler, the maximum
spacing is 30-inches/762-mm.
2b.
Apply light downward pressure, as
shown above, to maintain the position
of the end bracket flat against the T-bar
rail. To secure the end brackets to the
T-bar rails, tighten the pre-installed
sheet metal screws using a #2 recessed
square drive bit. Penetrate through the
T-bar rail until the end bracket is seated
fully against the T-bar rail.
DO NOT over-
tighten the screws. Over-tightening will
cause the screw to strip, resulting in an
unsecured bracket connection.
3. Complete the installation by following the applicable instructions in the “Sprinkler
Reducing Nipple Installation” section in this handbook.
