GENERAL NOTES
• The Allowable Hole Zone is suitable for uniformly
loaded beams using maximum loads for any
tables in the product guide. For other load
conditions or hole configurations, please
contact your GP Lam LVL representative.
• If more than one hole is to be cut in the beam,
the length of the uncut beam between holes
must be a minimum of twice the diameter of
the largest hole. No more than three holes
are allowed per span.
• Rectangular holes are not allowed.
• Holes in cantilevers require additional analysis.
• Required hole clearance and the effects of beam
deflection must be considered to prevent
problems with utilities that penetrate the holes.
• Maximum hole diameter is:
Do not cut, notch or drill
