INTRODUCING:
TRUSSES THAT POSITION AND ANCHOR THEMSELVES
With the GR-3 Self-Storing Framing and Uplift Anchor by GERRYRIGS LLC
The GR-3 is a primary framing connector for joining roof trusses, rafters or joists to supporting walls or beams.
This multi-function device provides placement guidance, lateral structural connection, uplift anchorage, and reduces splitting caused by heavy toe-nails.
The GR-3 may be positioned on the truss, rafter or joist at the time of fabrication or on-site prior to its placement in the building system. This advantage helps to increase accuracy of placement, speed of member installation and the safety of workers, adding up to labor cost reductions and minimized risk exposure.
There are other products in the market for uplift resistance but only the GERRYRIGS GR-3 Self-Storing Framing and Uplift Anchor provides multiple functions and code compliance with ease of use. The GR-3 is USER FRIENDLY.
Note: The uplift resistance of GR-3 far exceeds typical code requirements.* The 18 gauge GR-3 will exceed the Fortified Code requirements, which post Katrina now apply to coastal high wind zones.

GR-3 Method of Deployment:
With completed trusses stacked, prior to banding, or if on site, stacked trusses un-banded, prior to placement:
1. Verify the bearing point of the truss, and mark all trusses for placement of GR-3
2. Position GR-3 on the bottom chord such that the edge of the channel of GR-3 and the hinge-point of the uplift strap are at the inside face of the bearing member. If the trusses are in-stack, nail GR-3 through the bottom only, nailing through the sides just prior to lifting.
3. As the truss is lifted, the rigging worker can pry out the side tabs and deploy the uplift strap to 45 degrees. The partially deployed strap will serve to guide the truss into correct bearing position.
4. Bearing connections are made by nailing through the extended tabs and through the fully deployed strap.
Note: GR-3 eliminates marginally effective toe-nail connections, splitting of the bottom chord, and time lost jockeying into position. Also, if the connection must be freed in order to correct layout, etc, no damage to the truss will be incurred.
No separate operations are required for installation of uplift protection.
