NOTES:
1. Square and rectangular holes are NOT permitted.
2. Round holes may be drilled or cut with a hole saw anywhere within the hatched area
of the beam.
3. The horizontal distance between adjacent holes must be at least two times the
diameter of the larger hole.
4. Do not drill more than three access holes in any four foot long section of beam.
5. The maximum round hole diameter permitted is:
6. These limitations apply to holes drilled for plumbing or wiring access only. The size
and location of holes drilled for fasteners are governed by the provisions of the
National Design Specification® for Wood Construction.
7. Beams deflect under load. Size holes to provide clearance where required.
8. This hole chart is valid for beams supporting uniform load only. For beams supporting
concentrated loads or for beams with larger holes, contact Boise® EWP Engineering.
