attach header on max 24" bolt centers

Highest anchor installed at least as high as door opening.

Anchors to be evenly spaced between the header and the floor. Tabulted spacings apply to back jamb anchors only.

2x6 structural grade lumber. May be counterbored up to 3/4" deep at each anchor location to provide a flush mounting surface.

First anchor to start at no more than half the maximum on-center distance.

Alternative design may be approved by a registered professional engineer. Supporting structural elements shall be designed by a registered professional engineer for wind loads in addition to other loads. Calculation reference: DASMA TDS #161C, 2005 AF&PA NDS for Wood Construction and Simpson Strong-Tie data.
