Manufactured from start to finish at BLK BOX HQ, the BLK BOX 45° Hyper Extension incorporates the use of locally sourced laser-cut mild steel. This laser-cut steel offers stability and durability for the user throughout the entire duration of their workout. All steel is laser-cut on-site, before being welded, powder coated and assembled. A large number of parts are welded using robotic welding, while some parts require the detailed touch of our in-house welding team.

The high-density foam used on the 45° Hyper Extension offers the athlete a firm and stable cushioning throughout their exercise. High density foam padding features a highly durable vinyl leather cover, and offers a comfortable, firm and secure experience for the user. It can be easily wiped down and cleaned when necessary. 

The BLK BOX 45° Hyper Extension is coated in our signature textured anti-scratch powdercoat finish. It enters our internal industrial paint line, going through various stages of washing, drying, and painting before coming out freshly baked.

The 45° Hyper Extension also features rubber grip handles which allow the user to self-spot.
