Make your daily腰道具 lighter and more customizable.

The SmartBASE aluminum connecting custom chain is a customizable chain that attaches to plates, allowing you to freely layout腰袋, tool holders, and small item pouches.
Approximately one-third the weight of a stainless steel chain of the same size.
Reduces the burden on your waist during long hours on site, making movement, bending, and climbing easier.


It features a universal design that fits plates with a mounting pipe width of about 60mm.
Of course, it can be combined with SmartBASE plates, and is compatible with commercially available plates, allowing you to assemble your “ideal腰道具” as it is.

We have thoroughly refined even the smallest details that affect usability.
Uses hexagon socket bolts to reduce the risk of stripping screw heads, making tightening and customizing smooth.
A hex wrench is included, so you can make adjustments immediately upon receipt.
Also included as standard are spare long screws (axles) and nylon nuts, which are prone to wear.
Designed for easy replacement of consumable parts, allowing you to use it safely for a long time.
(*Nylon nuts are not reusable, so replacement is recommended.)

Adjusting the length to suit the site is also simple.
In addition to the included hex wrench, a screwdriver and a monkey wrench enable setup at the optimal length in one-unit increments.
Flexibly adapts to changing equipment or seasonal modifications.


Despite being lightweight, it ensures reliable strength.
Structural integrity confirmed by public agency testing up to approximately 270kg load (representative value).
Provides sufficient peace of mind for everyday腰道具 use.
The surface is finished with sandblasting under an anodized treatment, resulting in vivid coloration and excellent corrosion resistance.
