The Duraflex Roller Clamp Stud works in conjunction with the Roller Clamp Lock Nut 5/16 inch (DF-SF152) to hold the Duraflex Roller Clamp (DF-521) in place. Sold as one set with Roller Clamp Lock Nut (DF-SF152). Two are required per Roller Block.
Installation Tips: Make sure that the Roller Clamp Stud Lock Nuts are adjusted to the same tightness on both sides to ensure a quiet fulcrum that moves smoothly. When fine-tuning the tightness, use your wrench to turn the lock nuts 1/4 turn at a time until the correct adjustment is reached. When properly adjusted, you should NOT be able to move the Roller Clamp up or down at the contact point.
NOTE: Duraflex boards, stands and parts are NOT for residential use. Duraflex will not sell any boards, stands or parts to residential customers as residential pools are not designed to meet FINA (International Swimming Federation) guidelines.
