The wood plate is a dedicated plate for skin-friendly campus board training. Made from high-strength walnut wood, the edges are rounded and tapered. This taper reduces stress on the skin and provides an exquisite grip. Improved holding power dramatically increases your limit grade. Train your fingers with the wood plate and push your limit grade. Especially the 6mm is a high load. Set Contents: A set of 2 plates, each with a width of 11.7cm x height of 4.3cm and a thickness of 20mm. Includes dedicated wood screws (3.5 x 45mm) Notes: Do not use mounting screws with a shaft of 4.0mm or more. There is a risk of the plate cracking due to the load. For installation, use the included wood screws (3.5 x 25mm) or 3.8mm course thread screws (length 25mm or more). Tighten the final turn by hand. As the product uses natural wood, there may be slight variations in width and height. Custom sizes are also popular. (1500 yen per pair) Thickness can be made in 1mm increments from 3mm to 15mm. Sizes over 15mm are also possible. Examples: Thickness 7mm, 4mm, etc. Size changes: width 9.0cm x height 3.5cm, etc. Please inquire separately.
