Danback® Flexible Wood Backing


Danback® Flexible Wood Backing System, featuring Dricon® fire-retardant treated wood (FRT), has made wood backing installation easy and economical-eliminating cutting, notching, ripping and routing.

  • Provides extra screw pullout strength for heavy-duty backing applications
  • Available in 48” sections, for either 16“ or 24” on-center framing
  • Meets all specifications for commercial and residential applications

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:

  • Baseboards
  • Door Jams and Wood Trim
  • Cabinets and Vanities
  • Ceiling and Crown Moldings

Dricon FRT is pressure-treated wood that is chemically treated to reduce flamespread and smoke development.  Dricon is Class A fire retardant; it is EPA registered, ICC approved (ESR-1626) and complies with the 2012, 2009 and 2006 International Building Code (IBC) and the International Residential Code Council (ICC).

Danback flexible wood backing is available with FSC®-certified lumber and may contribute LEED® points to your project.
