4.3 USER CAPACITY:
The user capacity of this product is determined by its maximum static strength. Maximum static
strength is defined by the applicable standard or regulation and states the maximum static load that the product can
withstand. The maximum static load for your system must always be equal to or less than the product’s maximum static
strength.
;
When using this product, you may use one of the example configurations provided, or you may design your own
configuration using the described methods.
;
Maximum arresting force is limited by the user’s connecting subsystem.
A. USER CAPACITY - OSHA
To calculate your maximum static load, double the maximum arresting force of your connecting subsystem and add
twice the weight of any additional users beyond the first.
;
OSHA static load and static strength values as tested include a 2:1 safety factor.

See Figure 10 for reference. Each user’s primary subsystem must have a maximum arresting force less than or equal
to the limit for its mounting point, whether it is an eye bolt or mounting bracket.
The following example configurations may be used in compliance with these regulations.
