INTRODUCING:

TRUSSES THAT CAN SPACE AND BRACE THEMSELVES

With the GR-1 Self-Storing Component Brace by GERRYRIGS LLC.
The GR-1 is a spacing and bracing device for use in erecting wood or metal roof trusses or similar structural members, such as ceiling or floor joists, normally placed on regular centers. Fabricated from sheet metal and configured as a channel or “U” in order to nest over the truss or joist allows the GR-1 to be in a “stored position” on the truss or joist PRIOR to member placement in the building system. This unique feature results in greater safety, economy, and speed of unit installation.
Installed on the truss at the point of fabrication or on site prior to unit placement, use of the GR-1 means that bracing materials need not be procured, measured, cut, carried, passed up and secured in elevated unstable workspace, or moved forward as the truss system is set. Roof sheathing installs over the GR-1 so no labor is lost to remove, gather, clean or dispose of used bracing material.
The GR-1 is self-spacing, self-squaring, crimped into place with a hammer blow and then securely nailed. Available in 18 or 20 gauge galvanized steel the GR-1 can also be used for bottom chord bracing and for intermediate web member stiffening normally required in larger truss designs.
There are other products in the market for the spacing of trusses, but only the GERRYRIGS GR-1 Self-Storing Component Brace provides the ease of use that makes the process of erecting trusses safer and faster. The GR-1 is USER FRIENDLY.
Load Rated by SBCRI, GR-1 is certified to meet or exceed BCSI recommendations.

GR-1 Method of Deployment:

With completed trusses evenly stacked, prior to banding, or if on site, stacked trusses unbanded, Pre-install GR-1 on truss top chord and bottom chord members per BCSI recommended spacing.

1. Per lay out, place the GR-1 channel over the edge of the chord and hammer in place with the retaining teeth. Drive one nail through the pivot hole of one end of GR-1. It is now in “Stored Position”.
On the next and subsequent trusses in the stack, alternately off-set GR-1 by the length of the extending tab (this will prevent overlapping tabs when the GR-1 is deployed).

If on the yard, the trusses are now ready for banding and delivery. If on site, the trusses are now ready for placement.

2. As trusses are raised into place, lift GR-1 from “stored position” on the truss, to full 90 degrees.

3. Rotate 90 degrees, pushing the incoming truss away and then lower into position onto the preceding truss.

4. Crimp down the locking tab to capture the truss, and then nail through the pivot hole and through the tab. Nail the tab of the pivot end also. GR-1 and the trusses are now secured.

Note: With GR-1 deployed simultaneously from the top and bottom chords, the truss system is quickly and systematically stabilized and solidified.

Note: GR-1 can also be used to stiffen or interconnect web members as required by the truss design.
