What Stovetop Firestop does

Stovetop Firestop is the consumer-facing product line of WilliamsRDM, Inc., a family-owned, woman-owned manufacturer founded in 1972 and headquartered in Benbrook/Fort Worth, Texas. The company is the original inventor and patent holder of automatic residential cooktop fire suppression technology, holding three granted U.S. patents (7,472,758; 12,383,775; 10,821,311) with additional patents pending. Its three core products — Rangehood, Microhood, and LowPro — are mechanically activated canisters that deploy a proprietary dry powder formulation via gravity feed when flames contact a fuse or, in the Plus Sensor variant, when embedded sensors detect the characteristics of a grease fire. A 2017 product launch introduced sensor-based activation alongside the legacy fuse mechanism, while the more recent LowPro added a concealed design with adjustable arms for modern kitchen form factors.

Core offering

Stovetop Firestop (WilliamsRDM, Inc.) designs, manufactures, and sells automatic residential cooktop fire suppression devices that detect stove-top fires and discharge wet-chemical extinguishing agents without human intervention. Its flagship Rangehood and Microhood units install above ranges in single-family and multifamily kitchens, with related accessories (LowPro, Rangehood Adhesive Kit, Microhood Extension Bars) supporting installation. Products are patented, UL-listed, and assembled in Fort Worth, Texas using predominantly American-sourced materials.

Product overview

StoveTop FireStop is a family of automatic residential cooktop fire suppression devices. The core product line consists of three main products: Rangehood (the original, designed for installation inside range hoods), Microhood (for over-the-range microwaves), and LowPro (next-generation concealed unit for microwaves or flat-bottom vent hoods). These products work mechanically through fuse-based activation—when direct flame contact occurs, the canister deploys a dry powder to suppress grease fires. Accessories include Microhood Extension Bars and Rangehood Adhesive Kits for various installation scenarios. The company also manufactured legacy products including Range Queen (discontinued 1999), Plus, Plus LC, and Plus Sensor variants.

Scale indicators4 records

Recent moves6 records

Expansion highlights5 records

Direct peers

• iGuardStove: iGuardStove offers an intelligent stove-monitoring system that automatically shuts off burners after a period of inactivity. Like FireAvert, it competes for the same property-manager and senior-safety buyer StoveTop FireStop targets, though using motion-sensor-based prevention instead of fuse-activated suppression.
• FireAvert: FireAvert produces a smart plug that detects smoke or stove activity and automatically cuts power to the range. It addresses the same residential cooking-fire problem as StoveTop FireStop but via prevention rather than suppression, making it the most direct functional alternative for homeowners and property managers.

Broad incumbents

• First Alert (BRK Electronics): First Alert is a leading consumer fire-safety brand with deep retail penetration across hardware and big-box channels. Its household recognition in smoke and CO detectors makes it a relevant adjacent incumbent that could expand into kitchen-suppression or partner with multifamily developers alongside StoveTop FireStop.
• Whirlpool Corporation: Whirlpool is a major household appliance OEM whose ranges and cooktops increasingly include integrated safety features (auto shutoff, sensors). OEM-embedded safety could be either a long-term threat to standalone products like STFS or a partnership/distribution opportunity.
• Google Nest: Google's Nest Protect smoke/CO alarm represents the connected, smart-home paradigm for residential fire safety. While not a direct competitor today, Nest's platform strategy and ecosystem reach position it as a structural alternative path for consumers seeking integrated home safety versus standalone devices like StoveTop FireStop.
• Kidde (Carrier): Kidde, owned by Carrier, is one of the largest residential fire-safety brands in North America, primarily known for smoke and CO detectors. While it does not sell a direct equivalent to StoveTop FireStop, its retail distribution, brand recognition, and adjacency make it a credible future entrant into residential cooking-fire suppression.
• Ansul (Johnson Controls): Ansul, part of Johnson Controls, is the dominant supplier of commercial kitchen-hood fire suppression systems. While its products serve restaurants rather than residences, its category leadership in kitchen-fire suppression makes it the closest incumbent analog and the most likely acquirer or competitor if residential suppression regulation emerges.

Regional players

• Badger Fire Protection: Badger Fire Protection supplies commercial kitchen-hood fire suppression systems (under the Kitchen Knight and other brands) primarily across North America. It overlaps with STFS in kitchen fire suppression expertise and is a relevant reference point for scale economics in the broader category.

Emerging players

• Wallflower: Wallflower produces a smart plug and monitor that connects a stove to Wi-Fi and shuts off power if the cook leaves the kitchen. It targets the same unattended-cooking problem as STFS but with a connected, prevention-first architecture aimed at the multifamily and senior markets.
• Inirv: Inirv makes smart, retrofit stove knobs that sense smoke or inactivity and automatically shut off burners. It is a more consumer-electronics-flavored entrant in the residential cooking-fire-prevention space and overlaps with StoveTop FireStop's multifamily and senior-living applications.
