Fire Extinguisher Mounting Brackets for a Food Truck

A food-truck extinguisher purchase has two decisions: the rating your fire authority requires and the bracket Amerex lists for that exact model. The model-specific chart matters: an Amerex B500 and an A411 are both ABC extinguishers, but they use different vehicle brackets.

For most food trucks, start with an Amerex 810 vehicle bracket for a 20 lb A411 ABC (10A:120B:C per Amerex), plus a C260 Class K on its bracket if you fry. A compact truck using a 5 lb unit uses the 818; choose the B402 if your jurisdiction requires 3A:40BC, as Houston does. Match ratings to your jurisdiction’s text.

Who this is for, and who should skip it

This is for an operator choosing a portable extinguisher and a compatible vehicle mount. Read the jurisdiction section before choosing the extinguisher rating, then use the model chart to select the bracket.

Stationary storefront and boat installations are outside this guide’s scope; confirm their mounting and fire-protection requirements separately.

What actually determines the right bracket?

Use the exact model pairing in Amerex’s catalog, not agent weight or cylinder diameter alone:

Cylinder diameter (per Amerex)	Amerex extinguisher models	Bracket	Mount type (per Amerex)
4.25 in	B500/B402, 5 lb ABC	818	Vehicle/marine bracket
4.25 in	B500/B402, 5 lb ABC	818S	Two-strap vehicle/marine bracket
7 in	A411/423, 20 lb ABC	810	Heavy-duty box-type vehicle bracket
7 in	C260, 6 L Class K; C262, Class K	810	Heavy-duty box-type vehicle bracket

Amerex directly lists C260 and C262 with the 810. The A411 and C260 can each use an 810, but each extinguisher needs its own mount. These named pairings do not establish compatibility for every extinguisher with the same diameter or capacity.

Why the supplied wall hook needs a vehicle-mount check

Per Amerex’s current catalog, the B500 comes with an 888 wall bracket, the A411 with an 803 wall bracket and the C260 with an 816 wall bracket. The catalog lists the B500T separately with an 818; check the exact model suffix and supplied hardware.

For vehicles covered by 49 CFR Part 393, 49 CFR 393.95 states:

“The fire extinguisher(s) must be filled and located so that it is readily accessible for use.”

“The extinguisher(s) must be securely mounted to prevent sliding, rolling, or vertical movement relative to the motor vehicle.”

This is a retention requirement, not a categorical ban on every wall hook or a minimum strap count. Part 393 applies to vehicles meeting its commercial-motor-vehicle scope; it is not automatically a rule for every food truck or trailer. Confirm federal and state applicability to your vehicle and use the maker’s listed compatible mounting hardware.

Section 393.95 gives nonhazmat alternatives of one extinguisher rated at least UL 5 B:C or two each rated at least UL 4 B:C; a power unit transporting hazardous materials in a quantity requiring placarding needs at least UL 10 B:C. Those provisions do not replace the local food-truck requirements below.

How much fire suppression does your jurisdiction actually require?

These four named documents have different scopes and requirements. Confirm the applicable rating and installation with your fire authority or event organizer.

River Forest, Illinois

The Village of River Forest Fire Department requirements contain two conflicting ABC passages:

“One (1), 1.5 gallon (6 liter) Class K extinguisher and One (1), 3A:10BC extinguisher shall be mounted within the egress path.”

Later on the same page:

“All On-Street Mobile Food Trucks must have a minimum of a 4A:60B:C type portable fire extinguisher mounted conspicuously and the portable fire extinguisher must have had an annual test by a qualified technician. (NFPA 10 1-6.3)”

Confirm with the village which ABC requirement applies; the two passages should not be treated as one rating. The document also says:

“Portable fire extinguishers shall be maintained by a qualified technician at intervals not more than one year.”

“Where a fire suppression system is installed, an additional 1.5 gallon (6 liter) Class K portable fire extinguisher shall be located in the cooking area with a tamper seal intact and a current dated tag must be prominently displayed on the fire extinguisher.”

The first Class K passage is not limited to trucks with a suppression system. The gallon/liter wording above is the village’s wording.

Longview, Texas

The Longview Fire Department guide states:

“At least one portable extinguisher of the 2A10BC rating shall be accessible to the interior of the food truck/ Trailer.”

“Units utilizing oil/ grease fryers are required to have a Class K fire extinguisher on the unit.”

“All fire extinguishers require an annual inspection by a Texas licensed Fire Extinguisher Company. Required extinguishers must be properly mounted and readily accessible.”

Per Amerex, the B500’s 2-A:10-B:C rating matches this numeric ABC minimum. Matching a rating alone does not establish full installation compliance.

Groveland, Florida city events

The Groveland special-event rules state:

“Effective immediately, March 2025, the City of Groveland’s Fire Department requires all food trucks and trailers to be inspected and approved by the Fire Marshal before participating in any city events.”

“For food trucks that regularly operate in Groveland, inspections will only be required twice a year.”

“Requirements: Food trucks that do not cook, such as ice cream trucks, are not required to undergo an inspection but must have a fire extinguisher on board.”

“Fire Extinguishers: All mobile vending vehicles (trucks, trailers, etc.) serving food or with a heat source must have a certified fire extinguisher with a classification of 4-A:80-B-C.”

“It is strongly recommended that other vendors have one with a classification of at least 2-A:40-B-C.”

“Deep fryers are not allowed under tents.”

“FOOD VENDORS MUST SUBMIT AN APPLICATION FOR APPROVAL VIA PARKS STAFF AND OBTAIN FIRE MARSHAL APPROVAL BEFORE MAKING ANY PAYMENT(S)!”

These are city-event rules, not evidence of a standing citywide requirement outside that scope. This document does not separately state a Class K requirement; that omission is not a waiver of other applicable requirements.

Houston, Texas

The City of Houston Fire Marshal’s food-truck information states:

“All Food Trucks shall have one Type ABC fire extinguisher rated 3A:40BC.”

“If you deep-fry food, you must have a Type K fire extinguisher rated 2A:K.”

“All fire equipment shall be inspected, tagged, and unexpired.”

The B402 Amazon listing title gives 3A:40B:C, matching Houston’s stated ABC rating; the B500’s 2-A:10-B:C does not meet that minimum. Per Amerex, the C260 is rated 2-A:K, matching Houston’s Type K rating. Confirm the complete installation requirements, not just the label rating.

Longview and Houston both require Class K for the specified fryer use, without an occasional-frying exception in those passages. Per Amerex’s Class K product page, C260/C262 use a specially blended potassium acetate base agent and supplement automatic cooking-equipment protection.

Propane limits need their own scope check: River Forest states, “No mobile food vehicle may carry more than 40 pounds of total propane,” judged by rated tank capacity. Longview states, “LPG cylinders shall not exceed 100 pounds,” an individual-cylinder limit. These are different measures; propane quantity alone does not determine the required extinguisher type.

Amerex C260: Class K wet-chemical unit for fryer lines (required for fryers in Longview, TX and Houston, TX food-truck rules; check yours). Per Amerex, it holds 6 L, is rated 2-A:K, ships with an 816 wall bracket and pairs with the optional 810 vehicle bracket. Buy through a fire-equipment distributor: the Amazon C260 listing had no buy box and was not purchasable there as of October 15, 2026. Its portable protection supplements the automatic cooking-equipment system, per Amerex.

Where to mount it, and how often to check it

NFPA’s December 2024 placement fact sheet, based on NFPA 10 (2022), calls for visible, accessible locations normally along travel paths. It gives a maximum Class K travel distance of 30 ft from the cooking hazard, not a straight-line radius. River Forest separately requires the specified Class K and ABC units within the egress path.

For non-wheeled units, that NFPA fact sheet gives a maximum top height of 5 ft for extinguishers below 40 lb and 3.5 ft above 40 lb, with at least 4 inches of clearance below. Its summary wording does not resolve the exactly-40-lb boundary. Use total extinguisher weight, not agent capacity, and confirm the adopted edition and installation requirements with your fire authority.

The October 2020 NFPA inspection and maintenance guide, preserved by Utah’s government, describes inspection at initial installation and monthly afterward by a knowledgeable, competent person; certification is not required for that inspection. It calls for checking location, visibility, access, pressure indication and fullness by weighing or lifting, plus type-specific checks. Greater exposure to rust, impact or tampering warrants more frequent inspection. Monthly records identify the month/year and inspector and are retained at least 12 months; tags, paper or electronic records can serve.

That NFPA guide distinguishes annual external maintenance, performed by a certified person, from monthly inspection; internal examination intervals depend on extinguisher type, and discrepancies or hydrostatic testing can require additional maintenance. These are dated public NFPA summaries, not a substitute for your locally adopted edition or the named local service requirements above.

For non-affiliate record supplies, Brady 103632 is an aluminum inspection record; Brady instructs, “Use permanent marking pen or hole punch to indicate date of inspection.” SafetySign / Brimar offers the B2713-25 monthly inspection tag with inspection-date and signature fields and the B2706-25 annual-maintenance tag with name, address and signature fields. Per Brimar, both are vinyl tags supplied with nylon ties; the maker pages do not specify hole-punch suitability. A blank tag or monthly record does not establish that annual maintenance occurred.

For the rest of your truck’s fire and gas safety setup, see the food truck equipment checklist and the propane leak detector guide, or the propane tank warmer guide for cold-weather service. For the fuller category, start at the cafe equipment hub.

When planning the truck’s service opening, use the food truck serving window guide to compare sizes and code considerations.
