Description

The Northcore Lockjaw Centre Fin Lock is a simple bit of kit that can make a big difference when you need to leave your board unattended for a short time. Whether you are stopping for a coffee after a paddle, loading up after a surf, or leaving your board on the roof between stops, it adds a proper deterrent without being a faff to use.

It is designed for boards with a standard centre fin box, making it a practical choice for many longboards, surf SUPs and similar boards that use a removable centre fin. Instead of relying on luck and hoping your board is still there when you get back, this gives you a more secure and more reassuring way to lock it up.

Why choose the Northcore Lockjaw Centre Fin Lock?

  • Useful peace of mind: ideal when you need to leave your board briefly outside a van, on a roof rack, or near the beach.
  • Quick to fit: a straightforward security option that does not take ages to set up.
  • Built for the job: zinc alloy lock body with a PVC-coated marine cable for strength and rust resistance.
  • Good deterrent value: helps stop opportunistic theft, which is often what matters most in real-world use.
  • Board-friendly design: supplied with a padlock that includes a plastic base to help prevent knocks and dings.

How it sits in the range

This is a smart add-on for anyone with a board that uses a standard centre fin box and wants a more secure setup without moving to a much heavier or more complicated locking system. If you regularly travel with your board, leave it on a car between sessions, or want extra reassurance on day trips, this is one of those small accessories that is easy to justify once you have needed it once.

It is not a magic anti-theft solution and no lock can promise that, but for everyday use it is exactly the sort of practical deterrent that makes your board a far less easy target.

Will the Northcore Lockjaw Centre Fin Lock fit my board?

It is designed for boards with a standard centre fin box. If your board uses a non-standard system, it is worth checking before ordering. Northcore specifically notes that it will not fit Bic boards or similar pop-out boards that do not use a standard fin system.

Is this suitable for paddleboards as well as longboards?

Yes, provided the board uses a standard centre fin box. It is a good option for surf SUPs and other centre-fin board designs where you want a cleaner, more practical locking solution.

Does it guarantee my board cannot be stolen?

No lock can honestly promise that. What this does do very well is add a strong visual and practical deterrent, which is often enough to stop opportunistic theft.

Is it complicated to use?

No. This is one of the reasons it is popular. It is quick to fit, easy to keep in the van or car, and simple enough to become part of your normal post-session routine.

Specifications

  • Features

    Fits standard centre fin boxes
    The Lockjaw is made for boards with a standard fin box system. That makes it relevant for many longboards and centre-fin board designs where you want security without carrying bulky hardware.

    Zinc alloy lock construction
    This gives the main locking section a solid, durable feel and helps it stand up to repeated use in wet, salty environments better than cheaper, less thought-through alternatives.

    PVC-coated galvanised marine cable
    The supplied 2m cable is long enough for practical everyday use and the coating helps protect both the cable and the surfaces it comes into contact with. It is designed for marine use, so it makes sense around beach, paddle and surf environments.

    Quick fitting
    Northcore states it takes around 25 to 30 seconds to fit, which is important because security accessories only get used when they are quick and easy enough to become part of the routine.

    Padlock with plastic base
    A nice touch that helps reduce the chance of the lock hardware marking or knocking your board while you are setting up or moving things around.
