  • Do dual tab fins work in a GEARBOX 2?
    All dual tab fins are fully compatible with the GEARBOX 2 fin system, and will work without modification!
  • Can GEARBOX 2 be installed in EPS boards?
    The GEARBOX 2 system is fully compatible with EPS foam and can be installed using an epoxy resin. Care should be taken to ensure that the epoxy resin being used does not generate too much heat that could melt the EPS foam. This is more critical with the lighter density foams. See our installation guide for more information on EPS/Epoxy installations.
  • Minimum thickness required to install a GEARBOX 2?
    The routed depth of the hole for installing a GEARBOX 2 is approximately 5/8" (16mm) at the point of installation. it is advisable to have at least an 1/8" (3mm) of foam below the bottom of the box at the shallowest end. This means the board needs to be a minimum of 3/4" (19mm) thick at the point of installation.
  • What cant angles are available in GEARBOX 2?
    Currently, there are five different cant angles available - 0º, 2º, 4º, 6º, and 8º. There is a dedicated center box with 0º of cant.
  • Is sanding required before installation?
    GEARBOX 2 boxes are installed under the glass, so no sanding is required.

    If a box is being retrofitted to an existing board, then the area where the box will be installed will need to be sanded down in order to allow a couple of layers of glass to be placed over the installed box.
  • How tight do the screws need to be?
    The grub screws do not need to be overtightened in order to have a secure fit. All GEARBOX 2 fins have a recess in their bases into which the grub screws tighten, so all that is needed is for the screws to be snug with enough pressure to lock the fin into the box. The screws should be checked periodically as they tend to loosen slightly under load when the boxes are new.

    Over tightening the screws can cause them to strip the plastic, and is not necessary for a secure fit.
  • Do Futures fins work in a GEARBOX 2?
    Futures fins do not fit in a GEARBOX as their base is a lot longer than the slot in the box.
  • How is a GEARBOX 2 system installed?
    The GEARBOX 2 system is installed underneath the glass, so it is most commonly installed at the time the surfboard is laminated. The process involves routing the holes for the boxes first, then when it is time to laminate the board resin is poured in the holes and the boxes are installed, then the lamination begins immediately over the boxes. For more details on the installation process visit the installation guide on this site.

    In certain circumstances the boxes can be installed after the board has been laminated, but they will still need to be capped with glass to complete the installation. This is most commonly done when a board is being retrofitted with GEARBOX 2 or if a box is being replaced due to damage. But this approach could also be utilized in situations where the board is being colored and you do not want the color over the boxes.
  • How does the GEARBOX 2 system deal with fin cant?
    GEARBOX 2 is a fixed system so the cant angle is built into the slot of the box. We offer five (5) different cant angles - 0º , 2º, 4º, 6º, and 8º, plus a dedicated center box. Once the boxes have been installed in the surfboard the cant angle cannot be changed.
  • How is the cant angle identified on the boxes?
    There are three methods for identifying the cant angle of a box.

    1. On the top of load beam cover, centered on the outboard edge, is a small colored dot that indicates the cant angle. The color coding is as follows; BLUE - 0º, YELLOW - 2º, RED - 4º, BLACK - 6º, and PURPLE - 8º. The colored dot remains visible after glass has been applied over the box, making it easier to identify the cant angle. The dot is only present on the standard WHITE covers, color and custom covers do not have the dot!

    2. The cant angle is also embossed on the bottom of the slot in each of the boxes, this takes the form - 0º, 2º, 4º, 6º, and 8º.

    3. Starting in JAN 2016, there is also an indicator on the outside of the box, on the bottom. Takes the form of a circular embossed with the angle in large numerals - 0, 2, 4, 6, and 8. Center boxes have a 0 as there indicator!
  • Does the system have a separate center box?
    GEARBOX 2 has a dedicated center box with 0º cant that features opposing screws, as is commonly found in other systems. This center box is identical in shape to the side boxes so there are no special considerations for routing and installing the box. Except that the center line of the jig has to be used when positioning the box.
  • Does the system use a special installation jig?
    GEARBOX 2 does have it's own routing system, which consists of three separate jigs, these jigs are only used to rout the holes. In addition to the jigs there is also a special router bit that is needed that works with the jigs. Both the jigs and the router bit can be purchased as part of our installation kit.

    We DO NOT provide a router as part of the installation kit, this is something the builder needs to provide. We recommend using a trim router as they are inexpensive and easy to handle.
