Pemko R.5OSSMR_ Threshold Assembly

Offset Application (3-1/2" Top Plate)

  • Pemko modular ramps are ADA compliant as they meet the standard of a 1:12 slope.
  • The wings for these ramps do not meet the ADA 1:10 slope requirements.
  • In order to make the sides of the ramp ADA compliant, they must follow the ADA guidelines as follows:
  • Section 4.7.5 "Sides of Curb Ramps":
  • If a curb ramp is located where pedestrians must walk across the ramp, or where it is not protect by handrails or guardrails, it shall have flared sides; the maximum slope of the flare shall be 1:10.
  • Section 4.8.7 "Edge Protection":
  • Ramps and landings with drop-offs shall have curbs, walls, railings, or projecting surfaces that prevent people from slipping off the ramp.
  • Curbs shall be a minimum of 2" high.
  • Pemko recommends the use of mitered returns to seal up the side of the ramp.
  • Otherwise, we recommend filling and feathering the threshold ends with grout (do not leave threshold ends open).
