b. Girder with Ledger Board. Use a girder with a ledger board when vertical space is limited
and where more headroom is needed (see Figure 1-8).

c. Joist Hangers. A girder with joist hangers is used where there is little headroom or where
the joists must carry an extremely heavy load (see Figure 1-9).

1-3. Girder Size Requirement. A girder should be large enough to support the load. The carpenter
should understand the effect of length, width, and depth of the wood girder. The principles which
govern the size of a girder are--
The distance between girder posts.
The girder load area.
The total floor load per square foot on the girder.
