AnchorFLEX™ Flagship End-Link Strap Integrated look. Everyday simplicity.
Built for the Integrated Look
The AnchorFLEX™ Flagship—reimagined for a seamless fit.
Engineered specifically for Kumamoto™ end-links, this strap delivers a case-hugging, integrated profile with none of the complexity of a deployant system. Just a clean buckle, a locked-in silhouette, and nothing in the way.
Compatibility
✔ Compatible with Kumamoto™ end-links
✘ Not compatible with the Kumamoto™ clasp system
✔ Includes 316L stainless steel tang buckle
This is a standalone strap and is not part of the Kumamoto modular ecosystem.
AnchorFLEX™ FKM Fluoroelastomer
Our signature FKM compound isn't an afterthought—it's the foundation. Purpose-built for daily wear, it resists UV exposure, heat, and chemicals without hardening, fading, or losing its form. The result is a strap that feels broken-in from day one and stays that way.
Soft where it counts. Structured where it matters.
Flagship Design
Refined, not restrained. The Flagship profile tapers with intention—slim enough to complement a tool watch, polished enough to transition beyond it. This is the strap you reach for without thinking, and rarely take off.

FAQs
AnchorFLEX™ straps are made from premium FKM rubber and have been third-party tested to be free of harmful fluorinated “forever chemicals” within the scope of the testing performed. We do not intentionally add PFAS-based coatings, surface treatments, or chemical finishes to our straps. Because FKM is a fluorinated rubber, we avoid vague blanket claims and clearly disclose the material. Customers who prefer to avoid fluorinated rubber entirely may prefer our nylon, sailcloth, leather, or other non-FKM strap options.
Some end-link installs can feel tight at first because the thickness rubber strap at the end-link is maximized to ensure durability. There are a few ways to get it installed:
First, try gently wiggling and pushing the spring bar through until the spring bar pops into the opposite side of the end link. This can require some effort.
You can also squeeze the rubber portion of the strap into the end link between your thumb and index finger while pushing the spring bar into place. This helps compress the rubber slightly and gives the spring bar more room to seat properly.
If those techniques do not work, our premium 1.7mm spring bars can be used as an alternative. There is no downside to using them, but we recommend trying the first two installation methods first since the standard spring bars usually work once everything is seated correctly.
If you still have trouble, contact us and we can help troubleshoot the install.
