Modular Adjustable Breaching Frame – Freestanding
$16,808.27
The MBI-AF Adjustable Frame is a versatile breaching training frame designed to support realistic, high-repetition breaching operations using standard commercial or residential doors. Its adjustable rough opening allows instructors to accommodate multiple door widths while integrating seamlessly with the Breach Pro MBI-S Training System for ballistic, mechanical, hydraulic, and explosive breaching applications. Available in both freestanding and built-in configurations. MBI-S Training System sold separately.
Description
The Most Versatile Adjustable Breaching Frame for Tactical Training and Explosive Breaching Data Collection
The Modular Adjustable Breaching Frame – Freestanding (MBI-AF-FS) is a portable, full-scale breaching platform designed to provide military, law enforcement, and tactical training organizations with a realistic door breaching environment without the limitations of permanent breaching facilities.
Unlike traditional steel breaching doors that create unrealistic failure characteristics, the MBI-AF-FS utilizes standard residential and commercial doors installed within replaceable wood framing consumables. This approach delivers true-to-life door, jamb, and frame behavior during ballistic, explosive, hydraulic, and mechanical breaching operations while dramatically reducing training costs and reset times.
Built around a heavy-duty steel freestanding structure, the MBI-AF-FS provides agencies with a portable breaching frame capable of supporting high-volume training, explosive breaching validation programs, and repeatable data collection efforts.
Realistic Door and Frame Construction
The MBI-AF-FS was engineered to replicate the structural characteristics of real-world construction rather than forcing operators to train on unrealistic steel door simulators.
The system utilizes replaceable dual-layer 2×6 frame consumables that allow agencies to install standard residential and commercial doors while maintaining realistic frame strength and failure patterns.
With the standard dual-layer consumable configuration, the frame accommodates doors up to 36 inches wide. By removing a single layer of 2×6 consumables, agencies can install doors up to 39 inches wide, providing compatibility with many common law enforcement and military training requirements.
This design enables operators to train on the same types of doors they are likely to encounter in the field while maintaining repeatable and measurable training conditions.
Purpose-Built for Explosive Breaching Programs
The MBI-AF-FS is uniquely suited for explosive breaching training and explosive data collection programs.
Because the system utilizes real wood framing materials and standard door assemblies, agencies can evaluate charge placement, charge performance, frame response, and breach effectiveness under conditions that closely mirror operational environments.
The result is a training and testing platform capable of producing meaningful data while supporting realistic operator development.
Whether conducting explosive breaching certification courses, developing new charge designs, validating TTPs, or collecting performance data, the MBI-AF-FS provides a repeatable and scalable platform for program managers and breaching instructors.
Compatible with Every Major Breaching Method
While optimized for explosive breaching, the Modular Adjustable Breaching Frame is fully compatible with virtually every tactical breaching discipline, including:
• Explosive Breaching
• Ballistic Breaching
• Mechanical Breaching
• Hydraulic Breaching
• Thermal Breaching
• Training and Evaluation Programs
The freestanding design allows agencies to conduct multiple breaching methodologies on a single platform, reducing equipment requirements and maximizing training flexibility.
Portable and Deployable Anywhere
Many breaching programs are constrained by limited infrastructure and dedicated training facilities.
The MBI-AF-FS eliminates these barriers by providing a portable breaching frame that can be deployed virtually anywhere.
The system weighs approximately 700 pounds and can be transported by trailer, pickup truck, or utility vehicle. While four operators are recommended for setup and movement, the frame can be safely lifted using its structural steel header and does not require forklifts, cranes, telehandlers, or other heavy equipment.
This allows agencies to rapidly establish realistic breaching training environments at ranges, training centers, military installations, and temporary field locations.
Expandable Modular Architecture
The MBI-AF-FS serves as the foundation of the Breach Pro Modular Breaching Insert ecosystem.
The platform integrates directly with:
• MBI Door Panel Insert Receiver (MBI-DR)
• MBI Multi-Method Breaching Insert (MBI-M)
• MBI Frame Anchor (MBI-F)
• Hinge Side Breaching Inserts
• Additional Breach Pro training accessories
• Future Wall Breach Insert Modules
This modular architecture allows agencies to scale training capabilities over time while protecting existing investments.
