Seatbelt Fittings, Mounting Hardware & Accessories

Seatbelt Sales in Christchurch stocks a comprehensive range of seatbelt fittings and accessories to ensure every belt is correctly and securely installed in any vehicle or application. Whether you are fitting a new belt, replacing worn or corroded hardware, adapting an existing system to suit a different occupant, or adding seatbelt capability to a vehicle that was not originally fitted with one, we have the components you need.


Correct fitment of seatbelt hardware is not a detail to overlook. The loads placed on seatbelt anchor points in a collision are enormous, and hardware that is incorrectly sized, made from unsuitable material or fitted to the wrong structural point will fail under those loads. When hardware fails, the seatbelt fails, and the occupant is unrestrained at the moment they need protection the most. This is why we stock only appropriate-grade hardware and why our team is available to advise on correct fitment for your specific vehicle and application.


Seatbelt Sales has been supplying fitment hardware to drivers, workshops, fleet operators and industrial customers across New Zealand for decades. We understand the technical requirements, and we carry the range to support installations of all types, from a simple replacement bolt on a passenger car to a full industrial seatbelt mounting assembly on a piece of heavy plant.

Fittings & Accessories We Stock

Mounting Plates

Mounting plates are used to help fit aftermarket/General Purpose ELR seatbelts into cars where the original seatbelt made use of a longer mounting bracket. They come in a variety of lengths and are available in flat bent or captive nut options.

Anchorage Plates

Anchor plates used to distribute the load of a seatbelt anchor point across a larger area of the vehicle floor or body. Essential where the vehicle body does not have a dedicated seatbelt mounting point or where the existing mounting surface requires reinforcement to handle seatbelt loads safely.

Rivets

Rivets are used to hold anchor plates in position so that they do not move after the mounting bolt is removed. We supply rivets in appropriate sizes and grades for fitting seatbelt anchor plates.

Nuts, Bolts & Washers

We stock seatbelt-grade nuts, bolts and washers in the correct sizes and thread specifications for seatbelt mounting hardware. Using the correct fasteners is critical, as standard hardware store fixings are not rated for seatbelt loads and should never be used in seatbelt installations.

Spacers & Tube Nuts

Spacers and tube nuts are used to correctly position seatbelt anchor points relative to the vehicle body, ensuring the belt operates at the correct geometry for effective restraint. Correct belt geometry is important not just for comfort but for the belt to function as designed in a collision.

Tongue Stop Buttons

Small clips that prevent the seatbelt tongue from sliding down the webbing when the belt is unclipped, keeping it within easy reach for the occupant. A simple but practical accessory that improves the day-to-day usability of a seatbelt installation.

Droppers

Webbing or hardware components that adjust the height or position of a seatbelt anchor point, commonly used to improve the comfort and effectiveness of the shoulder belt for shorter occupants. A correctly positioned shoulder belt sits across the chest and shoulder, not the neck, and droppers help achieve that fit in vehicles where the standard mounting height is too high for some occupants.

Buckle Extensions

Buckle extension straps increase the reach of a seatbelt buckle, making it easier to clip in for larger passengers or in vehicles with limited buckle accessibility. Our buckle extensions are designed to maintain the performance of the original buckle mechanism.

Tether Straps

Used to secure the top of a forward-facing child restraint seat to the vehicle's tether anchor point. Tether straps are a mandatory part of correct child restraint installation in New Zealand and must be used in conjunction with the lower anchor connections for the restraint to perform correctly in a collision.
