LINE-LOCK ADJUSTABLE FIN: 

The Line-Lock Adjustable Fin features a 3 point adjustment system to allow exact fin 

positioning in any direction. The Line-Lock Fin is easily adjusted by loosening the 3 

set screws, positioning the blade in the desired position and then tightening the 3 set 

screws. O’Brien slaloms equipped with the Line-Lock fin are pre-set with the best 

overall fin position for that ski. Before adjusting the fin from the stock setting it is rec-

ommended to mark that position on your fin so that it can be easily positioned back to 

stock. Please refer to the chart below for suggested fin adjustments to help maximize 

the performance of your ski. Remember small adjustments will significantly change 

how your ski performs. 

A.R.C. 

(Adjustable Radius Control) FIN: The A.R.C. Fin features a performance blade with 

elliptical slotted screw holes for customized horizontal adjustments. The A.R.C. Fin is 

easily adjusted by loosening the 6 phillips head screws on the top of the fin, position-

ing the blade either further forward or back, and then re-tightening the 6 phillips head 

screws. Before changing from the stock setting it is recommended to mark that posi-

tion on your fin so that it can be easily positioned back to stock.

1. Do not leave your ski exposed to the sun or bad weather for long periods of time. 

We recommend purchasing and storing your ski in a slalom case when not in use.

2. Rinse ski after use to remove sand, dirt, and salt water. Do not clean ski with abra-

sive materials. Use only a soft cotton cloth.
