Why is there no chart page?

Clearance is a sum of job-specific distances, not a single code table reprint. The widget, guide, and manufacturer labels already give you the reference you need.

Does OSHA publish one universal clearance number?

No. OSHA 1926.502 sets system performance and criteria; your clearance comes from the equipment and geometry you actually use. Training expectations sit in OSHA 1926.503.

When should I prefer an SRL over a 6-ft lanyard?

Whenever available clearance is tight. See SRL vs shock-absorbing lanyard .

Is the 2 ft safety factor mandatory?

It is a planning margin in this tool, not a single OSHA “magic number.” Do not delete margin to force a pass. If the stack only works at zero margin, change the system.

Fall Clearance Calculator

Required fall-arrest clearance in feet — free fall + deceleration + harness stretch + safety factor vs available clearance below the anchor

Starting point, not a fall-protection plan — verify against OSHA, ANSI, and manufacturer specs before you clip in. Fall arrest clearance planning for construction is framed by OSHA 1926.502 (fall protection systems criteria and practices), equipment and system design expectations in ANSI Z359.1 (and the broader ANSI/ASSP Z359 fall-protection code family), and training requirements under OSHA 1926.503. Free-fall, deceleration, harness stretch, and safety-factor values must match the connector and harness you actually wear. This calculator does not replace a competent person, a written fall-protection plan, or the product labels on your SRL or shock-absorbing lanyard.
