Quick answer

The Fenix ALR-01 Tactical Flashlight Ring fits most of Fenix’s best-selling tactical flashlights with a tight, secure hold. It keeps your light’s belt clip in place thanks to slotted grooves, and its large finger ring works with gloves. If you run a compatible Fenix tactical light and want a more confident grip, the ALR-01 is a simple, low-cost upgrade.

Which Fenix flashlights work with the ALR-01?

Fenix states the ALR-01 is designed to fit most of its best-selling tactical flashlights. That means popular tactical models with a compatible body diameter and tail geometry will accept the ring. Because Fenix doesn’t publish a full compatibility list in the product details, the safest approach is to check your specific light’s body diameter against the ALR-01’s intended fit range or contact Fenix support with your model number before ordering. If you own a Fenix tactical light that uses a standard tail cap and body tube, there’s a good chance the ALR-01 will work.

How do I install the ALR-01 on my flashlight?

Installation is straightforward: the ring slides over the tail end of the flashlight body and is secured by the tail cap or a retaining ring, depending on your model. The slotted grooves are designed so you don’t have to remove the factory belt clip—the clip passes through the slots and stays functional. Tighten the tail cap firmly by hand; no tools are required. Once installed, rotate the ring to confirm it doesn’t spin freely and that the finger ring sits comfortably for your grip style.

Can I use the ALR-01 with gloves?

Yes. The large finger ring is specifically sized to be glove-friendly, so you can deploy and hold your flashlight confidently even with thick tactical gloves. That makes it a practical addition for cold-weather use, duty carry, or any situation where you don’t want to remove your gloves to get a secure grip.

Will the ALR-01 interfere with my belt clip?

No. Unlike some other brands’ rings that require you to remove the belt clip, the ALR-01 has slotted grooves that let you keep the flashlight’s belt clip installed. You retain the option to clip the light to a belt or pocket while still benefiting from the finger ring for a more secure hold during use.

Is the ALR-01 worth adding to a Fenix PD25R or LD30R?

If you carry a compact tactical light like the Fenix PD25R or LD30R and want a more confident grip, the ALR-01 adds real utility for a low price. It doesn’t change the light’s output or modes, but it can make one-handed operation and retention more secure, especially with gloves. For everyday carry where you rarely need a finger ring, it may be unnecessary; for duty, outdoor, or defensive use, it’s a sensible accessory.

ALR-01 quick FAQ

Will it fit my Fenix light?

It fits most best-selling Fenix tactical flashlights. Check your model’s body diameter or ask Fenix support if unsure. Confirm compatibility before ordering if you have an unusual model.
