The Stabilizer truss brace and spacer is truly
a breakthrough product. It provides
truss installers accurate 24 o. c. truss spacing with ample structural
properties for both construction bracing and permanent lateral bracing.
Its unique design means truss setting will never be faster or easier.
Just attach the Stabilizer to the top chord of an installed truss,
bring up the next truss and hammer down the top and side tabs.
Simple. No cutting and
handling spacer blocks or layout sticks.
No fumbling for nails hanging 30 feet in the air!
Since the Stabilizer is in-plane, you just deck right over the top of
it. In addition, the unique
structural quality of the Stabilizer allows it to be used as permanent
lateral bracing. The Stabilizer
is so quick to install, you can brace webs as you set trusses, eliminating the
need to return later to install lateral bracing..
THE STABILIZER TRUSS BRACE
Installation Guide and Product Specification
The Stabilizer is easily installed by embedding the patented MII 20
teeth on top flap straight into the edge of the truss member to be braced
with a framing hammer. The side tabs are then secured by driving the teeth
into the face of the truss member being braced.
Use The Stabilizer for standard 24" o.c.spacing. For odd spacing, cut and insert a solid block between the trusses.
Typically, The Stabilizer is installed at 6'-8' centers along the roof plane and 10'-15' along the ceiling plane. Refer to engineering specificaiton HIB-91, or DSB-89 (published by The Truss Plate Institute) for specific bracing requirement.
The Stabilizer must be supplemented with diagonal bracing in the roof
and ceiling planes and cross bracing in the web plane at required intervals.

<IMPORTANT: The erection contractor is responsible for determining and installing the temporary bracing for the structure, including the trusses. It is most important for the installer to provide adequate means for bracing the first truss installed. The performance of the entire bracing system depends on the adequacy of the ground bracing or other means of bracing the first group of trusses installed. The building designer is responsible for the permanent bracing design of the overall structure including the truss. This includes the design of required supplemental diagonal and cross bracing.
