Description
The Fox Labs Lock-On Grenade takes the same Five Point Three formula that law enforcement and military units lean on and puts it in a hand-thrown canister built for area coverage. You pop the locking top, toss it, and the unit discharges on its own while spinning across hard flat surfaces in a full 360-degree pattern. There's no need to stand there and hold a trigger, which is the whole point of a grenade-style unit. The 2% oleoresin capsicum formula is refined to a genuine 5.3 million Scoville Heat Units, which puts it well above the half-million to two-million range you'll see on most consumer sprays.
What the Fox Labs Grenade Is Built For
This one shines in confined-space and dispersal situations. Think securing a room, clearing a vehicle, or pushing a crowd back. Once the pop-top locks open the 3 oz canister empties itself in roughly 10 seconds, so you get a fast, high-volume cloud rather than a controlled stream. It's a different tool than a pocket keychain spray, and it's meant for folks who want sustained coverage over pinpoint aim.
Why the Lock-On Formula Stands Out
Beyond raw heat, the Fox Labs formula is oil-based and non-flammable, so it stays safe to deploy alongside a TASER or other electronic discharge device. It also carries an invisible UV marking dye that shows up under ultraviolet light, giving police a way to identify anyone who got hit. Fox stamps a manufacture date on every container and backs the spray with a 3-year shelf life, so you always know where your unit stands.
The canister is a durable black metal housing that measures about 4 inches tall and 1.5 inches in diameter, so it stays compact enough to stash in a bag or kit. Made in the USA at Fox Labs' Clinton Township, Michigan facility, this is a serious less-lethal option for trained users who need dependable, hands-off coverage.

Frequently Asked Questions
How do you use the Fox Labs Lock-On Grenade?
You depress the locking pop-top as you toss the canister, and the contents start discharging immediately. On a hard flat surface the unit spins in a 360-degree circle and empties itself in roughly 10 seconds, so you don't have to hold anything down. It can also be used as a standard spray unit if you'd rather direct the output.
How hot is the Fox Labs pepper grenade formula?
It uses the famous Fox Labs Five Point Three 2% OC formula, refined to a genuine 5.3 million Scoville Heat Units. That's well above the typical half-million to two-million range found on most consumer sprays, which is why it's trusted by law enforcement and military units worldwide.
Is the Fox Labs grenade safe to use with a TASER or stun device?
Yes. The oil-based formula is non-flammable, so it's compatible with TASER and other electronic discharge weapons. That makes it a practical part of an integrated less-lethal setup rather than a standalone-only tool.
Does the Fox Labs Lock-On Grenade have a shelf life?
Each canister carries a 3-year shelf life, and Fox stamps the manufacture date right on the unit so you can track it. Keeping an eye on that date and replacing it before it expires keeps your coverage reliable when you need it.
