Make your daily tool belt lighter and more customizable.

The SmartBASE Aluminum Linked Custom Chain is a custom chain that allows you to freely arrange your tool pouches, holders, and accessory pouches by attaching them to a plate.
Approximately 1/3 the weight of a stainless steel chain of the same size.
Reduces strain on your waist even during long workdays, making movement, bending, and climbing easier.


Universal design, compatible with plates with a mounting pipe width of approximately 60mm.
While it combines perfectly with SmartBASE plates, it can also be used with commercially available plates, allowing you to build your "ideal tool belt" by incorporating it into your current setup.
*Commercial items shown in product images are examples of compatibility and do not indicate a partnership with each company.


We have meticulously refined every detail that affects usability.
Features hex socket bolts that reduce the risk of stripping the screw head, allowing for smooth tightening and customization.
Includes a hex wrench, so you can adjust it as soon as you receive it.
Furthermore, spare long screws (shafts) and nylon nuts, which are prone to wear, are included as standard.
With a maintenance design that allows for replacement of worn parts, you can use it with confidence for a long time.
(*Nylon nuts cannot be reused and replacement is recommended)

Length adjustment to match your worksite is also easy.
In addition to the included hex wrench, with a screwdriver and monkey wrench, you can set the optimal length in 1-link increments.
Flexibly adapts to changes in attached items or seasonal equipment modifications.


Lightweight yet ensures reliable strength.
Structural integrity confirmed up to a load of approximately 270kg in tests by public institutions (representative value).
Provides sufficient peace of mind for everyday tool belt use.
The surface is finished with an anodized coating over a sandblasted base, resulting in a vibrant color and excellent corrosion resistance.
Choose from 7 color variations to match the tone of your equipment for a unified look or to add a pop of color.

"Your Day Changes.
Achieving both Lightweight and Practical Strength" Compared to stainless steel chains of the same size, the weight is a mere one-third.
Dramatic weight reduction significantly reduces daily fatigue.
On the other hand, strength tests conducted by public institutions have demonstrated a breaking load of approximately 270kg.
Ensures sufficient reliability for practical use.

"Beautiful Matte Colors Available in 7 Choices" Achieves beauty that stands out from any angle with fine polishing by sandblasting and vibrant colors from anodizing.
All 7 colors of beautiful matte finishes will brighten up your tool belt.

"Hex Socket Head "Resistant to Stripping"" To prevent the screw head from being stripped, which is common with Phillips (+) screws used in conventional products, the head has been improved to a hex socket type.
Includes a hex wrench, making maintenance, re-tightening, and customization work smooth.

"Spare Parts Kit Included as Standard" Includes a spare parts kit for nylon nuts, which cannot be reused, and long screws (shafts), which are relatively prone to wear.
You can safely use it for a long time as consumables can be easily replaced.
The spare kit includes the same number of nuts and screws as the main product.
For example, a 3-link chain comes with 4 nuts and 4 long screws.
Your own "ideal tool belt" that you arrive at after meticulous attention to detail.
