Block Set
A block set uses a rigid gauge of a stated width between the gripper handles before the final close. The term covers many starting positions; it is meaningful only when the block width is included.
Common format
The athlete uses both hands to position the gripper, then demonstrates that the specified block passes between the handle ends. After removing the block, the athlete completes the close with the designated hand.
Examples should be written as 20 mm block set, 30 mm block set, or another exact width. “Block set” alone does not establish how far the handles were allowed to close before the attempt.
Why blocks are used
A solid gauge is durable, easy to film and more repeatable than judging a visual parallel position. Blocks also allow a contest to offer different disciplines without changing grippers. A wider block preserves more sweep; a narrower block permits a deeper starting position.
The block's shape and the point where it is inserted matter. Official attempts must follow the organizer's specified gauge and procedure.
Block set versus credit-card set
A Credit Card Set is a standardized gauge set associated especially with IronMind. It can be understood as a particular wide-gauge format, but the established name and official card requirements make it useful to document separately.
Documentation
Show the block's stated width, a clear pass between the handle ends, removal of the block and uninterrupted handle contact. Do not infer a competition result from training footage unless every event rule was met.
