  • Integrated Hardware

    Spring straps are strong and can place undue stress on a post every time user dons and doffs. Constant pull can wear down or even tear posts commonly used for most rubber straps. With this in mind, Apollo spring straps are designed to install through wall of fins rather than attach to post.


    Permanent installation required.  Hardware runs through foot pocket. In most cases you will need to permanently remove post commonly used for attachment of rubber straps.  See manual for quick reference or step-by-step instruction for additional details.

  • Tech & Care

    • Spring Straps are stainless but not stain proof.  To ensure hardware remains cosmetically appealing and easy to work with, we strongly recommend occasional disassembly for more thorough fresh water rinse.  If staining is present, scrub lightly with brush.  If necessary, add a baking soda to water for more thorough scrub.
    • Use correct driver.  Current fitting is T20 (Torx 20), V.1 PH2 (Phillips Head 2).
    • If you coat screws with any substance, be aware that oils cause early deterioration in rubber.  Take care to remove residue from fins.
