Not all sizes are shown; other sizes are available. ** PSF Ratings and depths are based on short term exposure with excavation open a period of time equal to 24 hours or less. Consult manufacturer should long term exposure be required. Depths are based on A, B, C soil types described in OSHA's 29 CFR Part 1926 (Subpart P), with Type A not exceeding 25 PSF per foot depth, Type B not exceeding 45 PSF per foot depth and Type C not exceeding 60 PSF per foot depth. Determine actual soil pressures and consult Manufacturers Tabulated Data prior to each use. Safety Railing/Guard Rail Trench guardrails are constructed from 1.625" 13 gauge high strength tubes.
