SST-1 Truss & SE-1 Enclosure

The SST-1 is the primary choice for speaker support truss systems.
It is designed to work perfectly with our SE-1 speaker enclosure (backbox.)

If you want to use another make of backbox, then you must use our LST-2 speaker support truss.

The SST-1 & SST-1/18 Trusses will fit any speaker baffle with mounting holes spaced as shown, as well as Torsion Spring Grilles listed below. (All screws included)

SST-1 TRUSS ... Faster, Easier Installation

• Complies with the mechanical and acoustical requirements of U.L. 1480(UUMW) and U.L. 2043 test standard.
• Made of noncorrosive steel for strength and durability. Breakdown strength of over 100 lbs.
• Complete installation instructions with all purchased.
• SST-1 works with 2'x4', 2'x2', and 4'x4' lay-in type ceilings.
• When used with the 4' ceiling tile, use the Extender-Rails, Model ER-2/48 (see accessories page).
• SST-1/18 works with the 18" (20") x 60" lay in ceilings.
• SE-1 Speaker Enclosure will work with the SST-1, SST-4, and SST-1/18 Support Trusses.
• Philips-head screws (#8x1.25" white) are supplied. Screws up to 3" are available.
• AT-4 Adapt-O-Tabs are available to mount speaker to SST-1 or SST-1/18 without using grille. This allows the speaker to be placed directly on the ceiling tile. In most cases sufficient sound will penetrate the ceiling tile for good low-level sound distribution.
