Danback® Flexible Wood Backing System, featuring Dricon® or FlamePRO® fire-retardant treated wood (FRT), has made wood backing installation easy and economical-eliminating cutting, notching, ripping and routing.
Danback provides superior connection shear and pullout strength to support and meet even some of the heaviest loading conditions. Simply snap, flex and screw Danback into place. The patented hinge design actually flexes around the stud and snaps into place for a perfect fit-every time.
Perfect backing system for:
FlamePro® fire retardant lumber and plywood meets the requirements for FRTW listed in the International Code Council Acceptance Criteria ICC AC66 conforming with the International Residential and the International Building Codes (IRC & IBC). In Evaluation Report ESR-1626, ICC Evaluation Service found that Dricon® fire retardant treated wood complies with requirements for fire retardant treated wood described in the International Building Code®.
Danback flexible wood backing is available with FSC®-certified lumber and may contribute LEED® points to your project.

Notes:
1. Listed load values are nominal test load values, appropriate safety factors/resistance factors should be applied by the designer for calculating loads for intended use.
2. Shear / Offset (moment-rotation) Load refers to load directed in the plane of the wall.
3. Tension Load refers to load directed perpendicular to wall or plywood surface.
4. Tabulated loads include the contribution of 5/8" gypsum board.
5. Test loads were applied to the gypsum board and backing system through a 1/2" thick, 2-3/4" diameter steel plate secured with (4) #12 hex head screws.
6. Loads were applied directly through the steel plate or to a steel rod that cantilevered from the plate.
7. Typical failure mode in backing testing was the gypsum board failure.
8. 24-in o.c. stud spacing test results were similar/identical to 16-in o.c. test results.
9. Listed capacities are based on 68mils (14ga) 50ksi studs.
