SST-4 Speaker Support Truss is designed for all 3 �", 4", 5" speakers that have grilles with mounting holes as illustrated above. These are primarily fire alarm speakers.
The SST-4 Speaker Support Truss is the same size and construction as our SST-1 Truss, with the only difference being that the center hole accommodates four inch (4") speakers instead of the eight inch (8") speakers. Use the SST-4 for both screw-on type grilles and torsion spring grilles. Made of non-corrosive steel for strength and durability. The SST-4 has a break down strength of over 100 lbs.
When used with the 4x4 ceiling tile, use the Extendr-Rails, Model ER-2/48.
When using Torsion Spring Type Grilles, order the TSB-1 Torsion Spring Bracket to adapt the SST-4 for use with Torsion Spring Grilles.
Our popular and easy to install Speaker Enclosure, Model SE-1, works with the SST-4 Speaker Support Truss. Phillips-head screws (#8 x 1-1/4, white) are supplied. U.L. 1480 Listing Standard (UUMW) and U.L. 2043 Test Standard, for use in Air-Handling Spaces. Our SST-4 Speaker Support Truss (with or without our SAP-1 Speaker Adaptor Plate) when used in conjunction with our SE-1 Speaker Enclosure as illustrated below, will combine with any U.L. Listed speaker assembly in this configuration to make a complete assembly that is U.L. Listed for use in air-handling spaces.
