Upgrade your existing jumps or build new jumps to meet KC and UKA safety regulations of removable jump cups.
These jump cup inserts take the standard square peg cup (also available here) and are fitted simply using a 30mm drill bit.
They literally allow a square peg to fit in a round hole you have drilled and future proof your jumps in the event of a change in regulations.
Each insert has the standard 16mm square hole and sits virtually flush against the jump wing.
It couldn't be safer or easier.
