Grip Span Optimal Range Two-Handle Tool Checker
Intersect individually measured comfortable two-handle spans with actual adjustable tool range; explicit empty compatibility, no universal 5th–95th optimum or suitability approval.
Description
A comfortable measured grip-span interval can overlap an adjustable tool interval.
A comfortable measured grip-span interval can overlap an adjustable tool interval. A single shared endpoint counts as compatible.1
Enter two ordered positive millimeter bound pairs. Return their inclusive intersection or empty list and compatibility flag.
When to use Grip Span Optimal Range Two-Handle Tool Checker
Use Grip Span Optimal Range Two-Handle Tool Checker when you need to evaluate the supplied records under the calculation and evidence rules below. No universal optimum, population percentile or suitability approval is inferred.
Prepare measured task, body, furniture or already weighted exposure records. Supply independently verified caller policies, tables and comparison limits with matching units and conditions.
How to use Grip Span Optimal Range Two-Handle Tool Checker and understand its results
- Prepare measured task, body, furniture or already weighted exposure records. Supply independently verified caller policies, tables and comparison limits with matching units and conditions.
- Enter measuredComfortableGripSpanBoundsMm, toolAvailableSpanBoundsMm using the field table and calculation rules, then run the tool.
- Read compatibleGripSpanBoundsMm, compatibleGripSpanFound. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| measuredComfortableGripSpanBoundsMm | Measured comfortable grip span bounds mm | list of number | Required |
| toolAvailableSpanBoundsMm | Tool available span bounds mm | list of number | Required |
Enter two ordered positive millimeter bound pairs. Return their inclusive intersection or empty list and compatibility flag.
overlapLower=max(lowers); overlapUpper=min(uppers) Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| compatibleGripSpanBoundsMm | Compatible grip span bounds mm | list of number |
| compatibleGripSpanFound | Compatible grip span found | boolean |

}Limitations and assumptions
No universal optimum, population percentile or suitability approval is inferred.
Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Numeric lists are limited to 10,000 entries; string lists to 128 strings of at most 128 characters each. The rules above may impose smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors. A successfully returned false flag is an evaluated outcome; its meaning is explained above.
Alternative or Complementary methods
Use Grip Diameter Cylindrical Handle Fit Calculator (5th-95th percentile): A caller-calibrated handle-to-hand ratio creates an individual diameter interval. Observed sample fit should retain excluded subjects. For a complementary task, use Overhead Reach Limit Height Checker: Adjustable task heights and measured comfortable reach can share an interval. Fixed tasks above the upper reach limit are a separate check.
