The Spacer & Adapter is one of the alternatives for many drivers when they encounter the safety concern. As to the excessive length of the screw, the resilience of the screw, the redundant thickness of the mat, accompanied by the vibration of the car during the high speed, so there are a built-in screw with a central hole bushing shape, of CNC Spacer and Adapter.
SPR applies high-strength 6061 aluminum alloy and comes with SPR-selected special screws and locking nuts, ensuring the stability of the quality and fineness of the product. SPR also accepts to customize their products in various specifications, with 7 to 10 days lead time for the production.

The design of the Spacer & Adapter in the market can be seen generally similar. But what is rarely to be noticed is the focus of the product. In addition to the original center hole guide angle, each hole and each knife are carefully designed to have a gentle angle and will not hurt people.

The most special one is the special screw on the oval base:

Common products used in the market are generally round head extension nuts, and then through the internal teeth to bite the hole of the Spacer. Therefore, if the torque of the store's pneumatic wrench is too large, it is possible to make the screw slide like a normal aluminum alloy nut, causing it to idle on the Spacer.
In order to avoid such problems, SPR uses an oval adapter screw, which is matched with an oval screw hole, so that it is unable to idle at all - unless the entire Adapter & Spacer are broken.

These small designs create different brand images and values. SPR products give priority to quality and service, and safety is our priority.
